i think it would be OK to do half of this: make it easier to preempt 
a +nice task. Michel, do you really need the -nice portion as well? 
It's not a problem to super-preempt positively reniced tasks, but it 
can be quite annoying if negatively reniced tasks have super-slices.

This should do that (unless I need a stronger cup of tea).

cool - thanks Peter. Michel, could you check Peter's patch, does it 
resolve all the interactivity problems you've been seeing?
