It's sort of like using a callback rather than polling to deal with 
interrupts. (not literally, but the analogy works)

It's great for laptops because it helps preserve battery power. It _sounds_ 
like it might be a cool option for real time, but I've tried it and it caused 
all kinds of problems with real time performance. (It also totally hosed 
compiz)
