   Yes, same with where I worked; watchdog being a _hardware_ circuit that   
   would hard-reset the system unless it received input from time to time -   
   to avoid software latchups. My colleague with the sense of humour   
   thought of it as a real dog that would bark unless fed, and had   
   subroutines called things like "feed dog" and "wash dish".
