This would help X, but regardless mp3 playing should not skip. I think its giving newly forked children much too high a priority. Basically new children can't get less than 50% sleep time, which is stupid on my behalf because a program which continually forks children that do a little bit of work then exit would basically be at 50% sleep time when it should be at or close to 0.
