    I can accept the need to call pthread_mutex_lock() before dealing with a
    condition variable, but why must a shared resource be tested prior to
    calling pthread_cond_wait()? Suppose a wait-thread is expected to block
    until a shared counter reaches a certain value: why must it test for the
    condition first, before the call (assuming the condition is not met)?
