Para::Frame::Watchdog - Watches over the process
Makes sure that the daemon runs.
Restarts it if it eats too much memory or if it craches.
Called by Para::Frame/daemonize or Para::Frame/watchdog_startup.
Uses lsof
to check if another process uses our port, and tries to
kill it if there is any. Works fine for restarting your daemon.
This may shut down the server completely if restart fails... may want to handle this better
