There are no AS patches missing in vanilla. I don't think there are..
none that would change that.

Its unlikely that its an IO problem because its unlikely that your tar
would be evicting anything that X or the xterm depend on. If the
machine is swapping at this time then try setting /proc/sys/vm/swappiness
to 0.

Oh, you could try my cpu scheduler patch a try if you're bored.
