How do you usefully tell the difference between an application that's 
waking up a lot because it's dumb and an application that's waking up a 
lot because it's doing something useful? One downside of powertop is 
that it's resulted in a lot of "How do I reduce the number of wakeups 
caused by i8042 whenever I use the mouse"-type questions. We don't want 
innocent app writers to be hit by this kind of thing.
