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.

patch helps a little, I have to do some more work on the algorithm and make
it smarter to help a lot.
