So very true, this is a rule number one for designing high 
availability systems. One must assume that any single program is 
always doomed to fail and focus on designing whole system that 
will not. Duplication, various heartbeat watchdogs and fast 
recovery times for processes are key here.

Also nothing that is powered from the same power source can't be 
considered fail-safe. ;)
