setting timerslack to 0 has no real negative effects on the system on
the one hand, on the other hand, it'll be multimedia apps and games who
want to do this.
Requiring this type of app to be root doesn't sound like a good idea,
especially since all you get by "cheating" is ... the exact behavior
you ask for anyway. "Increased power consumption" isn't a root
privilege, the app can consume much more power just by a "while (1);"
loop for example.
