This is arguing on a very thin line. In fact it is becoming pointless. Suppose there were an RSS-feed plugin that signals events to an event Plugin. That event plugin could be either visual notification or sending audio-signals. But the RSS feed doesn't know what specific plugin it talks to. So screen off is _not always_ the right indicator. Sometimes it is, sometimes it's not. There would be a seperate infrastructure needed in the program to tell the different plugins that the core thinks everything should stop. How does the core knows when to stop? And then there probably need to be some kind of "suspend blockers" in the program. *g* Just solve it at the right level, so that the apps don't need to be infected with this shit. And this belongs between the iron and the apps. And it seems it needs to be some cooperative approach of kernel and userspace-framework as it isn't right to put that much policy in the kernel. I don't think it is a black and white thing, where you can just say "fix the friggin apps". And this is a really f*beep*ng serious point.
