A simple watchdog to monitor and keep alive a process. Your process should update a watch file such as `/var/tmp/myprocess.watchdog` at regular intervals. The watchdog checks this is being updated and if not assumes it is hung. The watchdog then attempts to kill any matching prcoesses and restart a new one.
