Hmm, I'm thinking there would not be any need to turn the screen on
for the broken apps until some other event such as a tap on the screen
triggers the need to turn the screen on.

If it's a critical app, then it should be fixed so it's safe to keep
running.

And yeah, I guess you could cgroups to categorize "timer certified"
and "broken" apps.
