Note that this doesn't work for fcron, anacron, and such without some
work.  But it's been behaving well at our site.  Defining the
RestartCrontab class didn't work reliably, so I always resubmit the
crontab (feeding a crontab to cron is the most reliable way of
ensuring it will recognize it, in my experience - the HUP signal is
the second most reliable way).

Parts of this are based on past discussion on the cfengine mailing
list.
