how does cron exec jobs?

[Atom Powers]

I have a cronjob ( cfexecd -F ) that often hangs; but no matter how I
run it from the shell ( sh -c "cfexecd -F" & ) it never hangs.
(Running it from the shell is how I clear the hung state.)

How can I simulate a cron job from the shell? There must be something
different about the way cron is executing this command...
