note that what I'm speculating about would never freeze some of the tasks,
it would run everything if anything is run, but it would not consider the
actions of some of the programs when deciding if it can shutdown.
so if you have all your privilaged applications in long sleeps, but still
have your bouncing cows running, peggng the CPU, making noise, and
updating the screen, the system would decide the system is 'idle' and go
into the 'suspend' low power state until there is a wake activity.
but if you have a privilaged application doing other stuff (say you are
talking on the phone, have a GPS mapping program running and giving you
directions, etc), the bouncing cows would continue to run and there would
never be an attempt to freeze them while leaving the other stuff active.
