There's a difference: it's completely correct for a thread-safe library
running in a non-threaded app to use pthread_cond_init(). It is also
correct to use pthread_cond_signal to signal that a condition is now
true. What isn't correct is to use pthread_cond_wait/timedwait() since
there is no way pthread_cond_signal() can ever be called.
