Hi Karl,
I knew this was going to come up when I added the scheduler, but I
didn't want to do anything about it right then. Thanks for doing the
work for me!
Off the top of my head, the code looks fine. The scheduler itself only
uses one thread no matter how many jobs you have scheduled. The
threads for the scheduled jobs *should* terminate when the job is
done.
