+-- OBJECTIVE:
+--      Check that two procedures in a protected object will not be 
+--      executed concurrently.
+--
+-- TEST DESCRIPTION:
+--      A very simple example of two tasks calling two procedures in the same 
+--      protected object is used.  Test control code has been added to the
+--      procedures such that, whichever gets called first executes a lengthy
+--      calculation giving sufficient time (on a multiprocessor or a
+--      time-slicing machine) for the other task to get control and call the
+--      other procedure.  The control code verifies that entry to the second
+--      routine is postponed until the first is complete.
