Hi,

yeah, tell me about it :-p

during development on MeeGo devices we try to tackle down as much as 
possible the use_time offenders and start by filing bugs to those apps, 
instead of fixing their issues in kernel space.

if suspend_blockers could at least be transparent to applications, then 
it wouldn't be the best scenario but at least applications wouldn't have 
to be specially written to support that. And like I said, if anyone can 
hold a suspend_blocker forever the idea of "improving use_time" is easy 
to break, but then someone replied "anyone holding a suspend_blocker 
will show up in UI", and again I say you don't need suspend_blockers to 
have a fancy UI showing which processes are waking up the processor. 
Powertop already gathers that information, you just need to make a fancy 
UI around it.
