+      * -------------------------------------------------------------------
+      * This routine creates an association that
+      * is unique for the given (thread,key) combination.The association 
+      * is referenced by both the thread and the key.
+      * This association allows us to determine what keys the
+      * current thread references and what threads a given key
+      * references.
+      * See the detailed description
+      * at the beginning of this file for further details.
+      *
+      * Notes:
+      *      1)      New associations are pushed to the beginning of the
+      *              chain so that the internal ptw32_selfThreadKey association
+      *              is always last, thus allowing selfThreadExit to
+      *              be implicitly called last by pthread_exit.
+      *      2)      
+      *
+      * Parameters:
+      *              thread
+      *                      current running thread.
+      *              key
+      *                      key on which to create an association.
+      * Returns:
+      *       0              - if successful,
+      *       ENOMEM         - not enough memory to create assoc or other object
+      *       EINVAL         - an internal error occurred
+      *       ENOSYS         - an internal error occurred
