+      *      NOTES:
+      *              1)      A condition variable can be destroyed
+      *                      immediately after all the threads that
+      *                      are blocked on it are awakened. e.g.
+      *
+      *                      struct list {
+      *                        pthread_mutex_t lm;
+      *                        ...
+      *                      }
+      *
+      *                      struct elt {

+      *                        int busy;
+      *                        pthread_cond_t notbusy;

+      *                      }

+      *                      }

+      *                      In this example, the condition variable
