   6  *    This test program validates the functionality of the
   7  *    ACE_Condition<ACE_Recursive_Thread_Mutex> template
   8  *    specialization when combined with the
   9  *    ACE_Thread_Timer_Queue_Adapter on Win32 and Posix pthreads.
  10  *    It was added to test for bugs with the ACE_OS recursive
  11  *    condition implementation.
