-  Title:       MULTIPLE ATEXIT() FUNCTIONS
-  Description: atexit() supports registration of only single function called on
-               exit().  It should support multiple functions registered by atexit()
-               or onexit() and these should be called in reverse order of
-               registration when the task exits.
