disable cpuspeed while X session active and screensaver not running

[Florin Andrei]

More cool stuff:
If there is an easy way to control cpuspeed, it would be nice to have 
some sort of dispatcher combine several types of events, make decisions 
based on them, and then send signals to cpuspeed, such as: "don't 
throttle the CPU, we're in the middle of something", or "go ahead and 
throttle, do what you want". Or even "something's wrong, force throttling".

It would be nice if applications had a way to communicate 
throttling-related info to such a dispatcher. E.g., let's say Qjackctl 
is running, and the user clicked on the Start button, so therefore jackd 
is running. In that case, even if the screensaver would later send a 
throttling request, it should be overriden by Qjackctl's own request 
that says "don't throttle, even if screensaver kicks in."
Something like a system of priorities.

I guess what I'm saying is - throttling is technically good, but it's 
something the users may not want, and because it looks like something 
that can be managed by a clever software, the burden of managing 
throttling should not be pushed onto the users.
