I gave this a try and my perception is that it helped a bit when switching
windows under high disk IO. It didn't seem to help much with programs
taking a long time to exit. I suspect this might be do to lots of dirty
pages stacking up and then a sync occuring. I'll try playing with the
value for how long they sit around and see if that helps some more.

Thanks for the help with setting the scheduler.
