Not curious at all. I should have made it clear I was in _no_ way recommending 
renicing X. It should be left at nice 0 and the scheduler decide what is 
interactive. Renicing X will guarantee you of getting audio skips. 

There is still the problem of apps started during heavy loads. While the last 
patch helps a little, I have to do some more work on the algorithm and make 
it smarter to help a lot.
