We can just as well have a class of tasks less important than power
saving. They'd just run when power saving is not active for some other
reason. Just like other such schemes we end up with the problem
of priority inversion with locking.

Ok, I guess this could be interesting in some cases... maybe. What are
real examples of such tasks?

Some people might put casual system monitoring tools into this  
category--top, xload, gkrellm, xclock, etc.

I guess system monitoring should stop itself when screen is
blanked... no need to compute list of processes if user can't see the
output.

But I see that may be slightly hard for command-line tool like
top. .... but it still seems like right solution. Why waste power/cycles
displaying xclock at tty9 when user is looking at tty10?

It'd be nice if the animated banner ad in my web browser could be  
treated this way. :)

Well, my web browser already has an option 'animate once'. No need to
waste power with that at all :-).
