-  /*

-   * Purpose:

-   *      This structure creates an association between a thread and a key.

-   *      It is used to implement the implicit invocation of a user defined

-   *      destroy routine for thread specific data registered by a user upon

-   *      exiting a thread.

-   *

-   *      Graphically, the arrangement is as follows, where:

-   *

-   *         K - Key with destructor

-   *            (head of chain is key->threads)

-   *         T - Thread that has called pthread_setspecific(Kn)

-   *            (head of chain is thread->keys)

-   *         A - Association. Each association is a node at the

-   *             intersection of two doubly-linked lists.

-   *

-   *                 T1    T2    T3

-   *                 |     |     |

-   *                 |     |     |

-   *         K1 -----+-----A-----A----->

-   *                 |     |     |

-   *                 |     |     |

-   *         K2 -----A-----A-----+----->

-   *                 |     |     |

-   *                 |     |     |

-   *         K3 -----A-----+-----A----->

-   *                 |     |     |

-   *                 |     |     |

-   *                 V     V     V

-   *

-   *      Access to the association is guarded by two locks: the key's

-   *      general lock (guarding the row) and the thread's general

-   *      lock (guarding the column). This avoids the need for a

-   *      dedicated lock for each association, which not only consumes

-   *      more handles but requires that the lock resources persist

-   *      until both the key is deleted and the thread has called the

-   *      destructor. The two-lock arrangement allows those resources

-   *      to be freed as soon as either thread or key is concluded.

-   *

-   *      To avoid deadlock, whenever both locks are required both the

-   *      key and thread locks are acquired consistently in the order

-   *      "key lock then thread lock". An exception to this exists

-   *      when a thread calls the destructors, however, this is done

-   *      carefully (but inelegantly) to avoid deadlock.

-   *

-   *      An association is created when a thread first calls

-   *      pthread_setspecific() on a key that has a specified

-   *      destructor.

-   *

-   *      An association is destroyed either immediately after the

-   *      thread calls the key destructor function on thread exit, or

-   *      when the key is deleted.

-   *

-   * Attributes:

-   *      thread

-   *              reference to the thread that owns the

-   *              association. This is actually the pointer to the

-   *              thread struct itself. Since the association is

-   *              destroyed before the thread exits, this can never

-   *              point to a different logical thread to the one that

-   *              created the assoc, i.e. after thread struct reuse.

-   *

-   *      key

-   *              reference to the key that owns the association.

-   *

-   *      nextKey

-   *              The pthread_t->keys attribute is the head of a

-   *              chain of associations that runs through the nextKey

-   *              link. This chain provides the 1 to many relationship

-   *              between a pthread_t and all pthread_key_t on which

-   *              it called pthread_setspecific.

-   *

-   *      prevKey

-   *              Similarly.

-   *

-   *      nextThread

-   *              The pthread_key_t->threads attribute is the head of

-   *              a chain of associations that runs through the

-   *              nextThreads link. This chain provides the 1 to many

-   *              relationship between a pthread_key_t and all the 

-   *              PThreads that have called pthread_setspecific for

-   *              this pthread_key_t.

-   *

-   *      prevThread

-   *              Similarly.

-   *

-   * Notes:

-   *      1)      As soon as either the key or the thread is no longer

-   *              referencing the association, it can be destroyed. The

-   *              association will be removed from both chains.

-   *

-   *      2)      Under WIN32, an association is only created by

-   *              pthread_setspecific if the user provided a

-   *              destroyRoutine when they created the key.

+   * Purpose:
+   *      This structure creates an association between a thread and a key.
+   *      It is used to implement the implicit invocation of a user defined
+   *      destroy routine for thread specific data registered by a user upon
+   *      exiting a thread.
+   *
+   *      Graphically, the arrangement is as follows, where:
+   *
+   *         K - Key with destructor
+   *            (head of chain is key->threads)
+   *         T - Thread that has called pthread_setspecific(Kn)
+   *            (head of chain is thread->keys)
+   *         A - Association. Each association is a node at the
+   *             intersection of two doubly-linked lists.
+   *
+   *                 T1    T2    T3
+   *                 |     |     |
+   *                 |     |     |
+   *         K1 -----+-----A-----A----->
+   *                 |     |     |
+   *                 |     |     |
+   *         K2 -----A-----A-----+----->
+   *                 |     |     |
+   *                 |     |     |
+   *         K3 -----A-----+-----A----->
+   *                 |     |     |
+   *                 |     |     |
+   *                 V     V     V
+   *
+   *      Access to the association is guarded by two locks: the key's
+   *      general lock (guarding the row) and the thread's general
+   *      lock (guarding the column). This avoids the need for a
+   *      dedicated lock for each association, which not only consumes
+   *      more handles but requires that the lock resources persist
+   *      until both the key is deleted and the thread has called the
+   *      destructor. The two-lock arrangement allows those resources
+   *      to be freed as soon as either thread or key is concluded.
+   *
+   *      To avoid deadlock, whenever both locks are required both the
+   *      key and thread locks are acquired consistently in the order
+   *      "key lock then thread lock". An exception to this exists
+   *      when a thread calls the destructors, however, this is done
+   *      carefully (but inelegantly) to avoid deadlock.
+   *
+   *      An association is created when a thread first calls
+   *      pthread_setspecific() on a key that has a specified
+   *      destructor.
+   *
+   *      An association is destroyed either immediately after the
+   *      thread calls the key destructor function on thread exit, or
+   *      when the key is deleted.
+   *

+   *              reference to the thread that owns the
+   *              association. This is actually the pointer to the
+   *              thread struct itself. Since the association is
+   *              destroyed before the thread exits, this can never
+   *              point to a different logical thread to the one that
+   *              created the assoc, i.e. after thread struct reuse.
+   *
+   *      key
+   *              reference to the key that owns the association.
+   *
+   *      nextKey
+   *              The pthread_t->keys attribute is the head of a
+   *              chain of associations that runs through the nextKey
+   *              link. This chain provides the 1 to many relationship
+   *              between a pthread_t and all pthread_key_t on which
+   *              it called pthread_setspecific.

+   *      prevKey

+   *
+   *      nextThread
+   *              The pthread_key_t->threads attribute is the head of
+   *              a chain of associations that runs through the
+   *              nextThreads link. This chain provides the 1 to many
+   *              relationship between a pthread_key_t and all the 
+   *              PThreads that have called pthread_setspecific for
+   *              this pthread_key_t.
+   *
+   *      prevThread
+   *              Similarly.
+   *
+   * Notes:
+   *      1)      As soon as either the key or the thread is no longer
+   *              referencing the association, it can be destroyed. The
+   *              association will be removed from both chains.
+   *
+   *      2)      Under WIN32, an association is only created by
+   *              pthread_setspecific if the user provided a
+   *              destroyRoutine when they created the key.
