this does not appear to happen, at least with the current incarnation, make -j5 jobs of the kernel tree (on UP), with your patch alone are hoovering at a considerably higher dynamic priority than they are with my patch. But interactivity itself is good as far as i can tell, in both cases - but i think Andrew would be a better tester in this regard.
plus my patch doesnt really change the core CPU-hog detector, what it does is that it changes the way children/parents will inherit priorities, plus changes the order of how children get their first timeslice. The end-effect is that the 'CPU-hog' make job is better recognized as that - but X itself will not be recognized in any different way.
