Thanks Mike. I tried:
renice -20 -p `pgrep mpd`
but my Athlon 2.2Ghz still can't handle it for more than a few
seconds. I don't have SMP enabled because of a bug in madwifi, and
I'm hoping when I get that fixed I'll be able to run the best
libsamplerate resampler. Any other ideas for making this work?
