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.
