	That's what Cris Wilkes suggested.  I didn't know that such a thing
existed, but it looks like it should do the trick. :)  Thanks to you both.

Is this a unix box?  If so, rather than creating the
daemon watchdog, why not run the daemon from DJB's
supervise (http://cr.yp.to/daemontools.html), or
from init (/etc/inittab) directly?  Either will be
able to automatically restart it if it stops, and
then you don't need to write another program and
it'll check constantly, rather than when cron starts
it up.
