-   * We know that static mutexes will not be PROCESS_SHARED

-   *
-   * If using a single global lock slows applications down too much,
-   * multiple global locks could be created and hashed on some random
-   * value associated with each mutex, the pointer perhaps. At a guess,
-   * a good value for the optimal number of global locks might be
-   * the number of processors + 1.
