Then I tried 2.6.0-test1-mm2, and several things happened: now scrolling an HTML page in Mozilla seems not to affect MP3 playback with XMMS, but this is the only possitive effect. Focusing windows raises them way slower than in 2.6.0-test1, scheduler starvation is constant (just try to do something like going to another virtual desktop), and then, after several minutes, only XMMS got CPU time, the rest of the applications (at least, those running over X-Window) get stalled.
