2012-10-05Unlock mutex before going back to waiting for PI mutexesSiddhesh Poyarekar
[BZ #14417] A futex call with FUTEX_WAIT_REQUEUE_PI returns with the mutex locked on success. If such a successful thread is pipped to the cond_lock by another spuriously woken waiter, it could be sent back to wait on the futex with the mutex lock held, thus causing a deadlock. So it is necessary that the thread relinquishes the mutex before going back to sleep.
