If you want to guarantee the service even in case of crashes (which
may not necessarily be core dumps, but could also be uncaught
exceptions), I'd recommend to put a super-simple watch daemon along
with service; if the service stops, the daemon should restart it. In
the service itself, assume it will run forever (until told to shut
down from the outside). 

Also put another computer next to the first one, to detect when the
entire computer crashes. Actually, don't put it next to it, but put it
in a different country, to deal with power outages and loss of network
connectivity :-)
