 Last update: $Date: 2002-09-02 09:37:48 $
 ------------

 System termination:

   the main task create J1, J2 and wait until 1 sec., then it calls sys_end
     and cycles around a task_testcancel

   J1 is a system task that ends at t=1.5 sec.

   J2 is another user task that dies at t= 1.8 sec (it will not die!!!)
