As another example, your CPU sometimes disables interrupts while it's 
processing one because what it's doing is too time-bound to be broken 
into.  If something happens and it hangs, even pushing the reset button 
(assuming your box has one) will work; it takes power cycling.  I had 
that happen, occasionally, when I was doing tech support and I'd have to 
tell callers to pull the power cord for a few seconds.  (It also 
happened to my own box once or twice, years ago.)  Once, the computer 
was a laptop and the caller had to go hunt up a screwdriver to take the 
battery out.
