This is crazy - the magic value is 172 rather than 1297437765 but the
fio_mutex_up() function is protected by an assert that checks to see if
the mutex's magic number is wrong. Could you can insert something like
the following after line 149:
assert(mutex->magic == FIO_MUTEX_MAGIC);
to prove that the value has not been stomped on before
pthread_cond_signal is run?
