+	* pthread_mutex_lock.c (pthread_mutex_lock): The new atomic exchange
+	mutex algorithm is known to allow a thread to steal the lock off
+	FIFO waiting threads. The next waiting FIFO thread gets a spurious
+	wake-up and must attempt to re-acquire the lock. The woken thread
+	was setting itself as the the mutex's owner before the re-acquisition.
