And, when the periodic wakeups are faster than the refresh time of powertop, no, powertop won't help you find the crapplication.   If you think that's acceptable, fine --- we'll see who wins in the marketplace, and who gets blamed for producing a crappy platform --- the incompetent application programmer, or the platform supplier.

Well, yes, if the company strategy is to have a walled garden ala the Apple iPhone App store, life is much simpler.   But if the requirements mean that apps don't need preapproval, the requirements on the platform get harder.   I think the take-home here is we have a requirement that the platform behave well even without someone screening the applications for the "default SW repository".
