I haven't thought about that yet, but I think we _will_ have to think up something to make the current scheduler more responsive and more predictable under load and to reduce the CPU time used by niced tasks.
I think that even without the priority heap we can use the Quantum/Defer model in order to get better predictability and responsiveness under load.
