condition.wait() or condition.timed_wait()

  Version: Boost 1.40.0 | Severity: Problem
 Keywords: condition |
--------------------------------------------------+-------------------------
 You can see in the attached project's TestBoostThread.cpp file that in
 ThreadFuncWaiter(), the thread is in timed_wait() call before it releases
 the mutex to let the ThreadFuncNotifier() thread notify it. But inside
 notify_one(), most of the time it will choose not to notify any "waiter".
 The total_count class member is 0 when that happens. If I uncomment the
 three lines marked as WORKAROUND_ in TestBoostThread.cpp, then the threads
 will be notified, but this is just a workaround.
