basically, a very-high priority timer is set up, and all that's done when 
it fires is check whether the system clock (which is driven by a 
lower-priority interrupt) has progressed. If the clock does not progress 
for a given number of times the timer fires, we assume the machine is hung 
and panic the machine.
