Time Manager tasks and as foreign functions

["M. G. Slack" <slack@starbase.mitre.org>]

Has anyone ever setup a periodic task using the time manager system from within
a foreign function call?  I've made a couple of attempts but the system crashes
instantly.  My test was trivial ... setting a periodic task up which increments
a counter every n-milliseconds and then each time the ff is called it returns
the  count.  I can get the code to run as a standalone c program but not as a
ff.  I'm guessing that it has somthing to do with setting and restoring the A5
environment.  Any leads?
