Only 'better' if that solution meets a need that's not met by the
straightforward approach.

I see that Timing Event Handlers are meant to be executed directly by
the protected handler operation
(http://www.adaic.com/standards/05rm/html/RM-D-15.html
25/2), so
clearly the intent is that some task should be released by the action
of the handler (similar to interrupts). So you still need explicit
tasks! just replacing a delay with a blocking wait on the PO which
will be triggered by the timing event -- a lot of complication.
