Comment 6 for bug 599425

I'm not having a battery and I don't see desktop-couch causing that many wake-ups, but I do see mutter randomly hogging the CPU for no apparent reason (causing up to 100% load). It usually happens when starting programs or switching between windows and stops when closing a couple of programs. I also had the system in a state where just moving the mouse caused mutter to spike between 50 and 80 % CPU load - I'm sure all that can drain a battery pretty fast.
