Without this patch, audio skips horribly when I drag a large window. With it,
audio is skipless during window dragging, so I like this patch, whatever it
does (maybe you'd like to do a victory lap and re-explain the theory?). It's
not perfect: in Mozilla, scrolling through a long page with the mouse still
causes skipping.

I'm testing this on a AMD K7 1666 (actual) MHz, 512 MB, VIA VTxxx chipset,
Software is 2.5.73+Gnome+Metacity+ALSA+Zinf. Video hardware is S3 ProSavage
K4M266, running in unaccelerated VGA mode, 1280x1024x16. Yes, I know audio
skips less if video is accelerated, IDE runs in dma, etc, but that's not a
real solution to this soft realtime scheduling problem.
