Not really a perl question, per se, but OK. If

1. You are lazy (and if you are a programmer, you probably are)
2. You are running on *nix
3. The restart does not have to be immediate
4. You don't need to have logic to diagnose chronic/constant failures

Then add a cron job that runs every couple of minutes and starts it if it is not there. Not pretty, but 15 minute's work, tops.
