Depends on which type you're talking about.
Some (most?) watchdog/procdoc type systems start two processes that watch each other in addition to the target process(es).

When writing these for my own daemons I usually make an "undead mode" where a monitor daemon is created to watch the service daemon, and the service daemon itself acts as the monitor for the monitor daemon.
