/* We may end up with a situation where lock_word is
0 but the OS fast mutex is still reserved. On FreeBSD
the OS does not seem to schedule a thread which is constantly
calling pthread_mutex_trylock (in mutex_test_and_set
implementation). Then we could end up spinning here indefinitely.
The following 'i++' stops this infinite spin. */
