Indeed knopwatchd shouldn't normally be necessary, and there are good pieces of software that are designed to monitor daemons are restart them if necessary. fwknopd is extremely stable from what I've seen. I'll take a look at upstart a bit - would probably be good to know if the restarting capability works well.
