 * Thread Specific Data (TSD) key management has been ammended to

+eliminate a source of (what was effectively) resource leakage (a HANDLE
+plus memory for each key destruct routine/thread association). This was
+not a true leak because these resources were eventually reclaimed when
+pthread_key_delete was run AND each thread referencing the key had exited.
+The problem was that these two conditions are often not met until very
+late, and often not until the process is about to exit.

+The ammended implementation avoids the need for the problematic HANDLE
+and reclaims the memory as soon as either the key is deleted OR the
+thread exits, whichever is first.

 Thanks to Richard Hughes at Aculab for identifying and locating the leak.
 
 * TSD key destructors are now processed up to PTHREAD_DESTRUCTOR_ITERATIONS
-times (was always in pthread.h) instead of just once.

 * Fix a semaphore accounting race between sem_post/sem_post_multiple
 and sem_wait cancellation. This is the same issue as with
