I forgot to mention, the script resides in the Zope directory. It *does*
work for a while (i.e., finds ./start like it should) then complains that
it can no longer find ./start

infinite loop script that sleeps fails? I don't get it. Thanks for pitching
in. If you have more ideas, please lay them on me.
