The reality is that if somebody raises a signal (an actual Unix
signal, not the things we have been discussing so far in this thread)
on the process that is running this code and pthread_cond_wait() is
interrupted, the program will act unpredictably.  I still contend that
nearly any call to pthread_cond_wait() that is not enclosed in a
proper loop is incorrect.
