   Version:  Boost 1.35.0                      |    Severity:  Showstopper                                       
Resolution:  invalid                           |    Keywords:  pthread_cond_wait condition variable pthread mutex
-----------------------------------------------+----------------------------
Changes (by anthonyw):

  * status:  new => closed
  * resolution:  => invalid

Comment:

 Note that the same internal mutex is locked in both notify_one and
 notify_all. It is not possible to call pthread_cond_signal or
 pthread_cond_broadcast through the boost::condition_variable_any interface
 whilst a waiting thread is in the gap you highlighted.
