     Release the locked \a mutex and wait on the thread event object.
     The \a mutex must be initially locked by the calling thread. If \a
     mutex is not in a locked state, this function returns immediately.
     If \a mutex is a recursive mutex, this function returns
     immediately. The \a mutex will be unlocked, and the calling thread
     will block until either of these conditions is met:
     \list
     \i Another thread signals it using wakeOne() or wakeAll(). This

     \endlist
 
     The mutex will be returned to the same locked state. This function
     is provided to allow the atomic transition from the locked state
     to the wait state.
