 * Test that pthread_getspecific()
 *
 *  shall return the value currently bound to the specified key on behalf of the calling thread.
 *  Calling pthread_getspecific() with a key value not obtained from pthread_key_create() or
 *  after key has been deleted with pthread_key_delete() is undefined.
 *
 * Steps:
 * 1.  Create NUM_OF_KEYS pthread_key_t objects
 * 2.  Set each key to a thread-specific value with pthread_setspecific()
 * 3.  Call pthread_getspecific() on each key and check that the value returned is correct.
