        test   :  TestMonitorThread

        Author :  Trent Jarvi

        added  :  Sat Oct 13 17:45:31 MDT 2001

        Problem:  Monitor Thread didnt go away in the past.  This makes sure

                  the thread does exit and is GC's.  You can watch the threads

                  in a native threads jvm with top.

        todo   :  There are still some issues with the way BlackBox open/closes

                  the ports and the removal of the eventListener.
