watchdog   [on | off]

        Display or set the watchdog timer.

        If internal operations cease for 300 seconds and watchdog is
        enabled, a system reset is performed.  This is useful for remote
        sites.  Note that in places, Jnos calls the memory allocator
        and waits for memory to become available.  It is possible for
        Jnos to deadlock, when no process is available to terminate and
        release memory to the allocator.  Hence the utility of the watchdog
        timer!
