Could this be what's killing off I/O in general lately? I used to be
able to compile and serve up files via NFS / samba without my
desktop/laptop skipping a frame of decent quality video over my
gigabit ethernet here at home, but now it appears to have gone
downhill a bit (well, that's what I noticed since my last update which
was ~14 days ago, e.g. BETA1 -- I just updated tonight so we'll see
what happens now...).

Thanks HPS!
