+ * 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.
