The sound skipping went away a while ago, but desktop performance is
still lousy while compiling on a UP machine. Fiddling with X's rtprio
can more or less fix the problem, but it's a pain to do it manually each
time. If it were a scheduler issue, it would seem like the priority of
make isn't getting bumped down enough and its children aren't being
spawned with the appropriate lower priority - but it happens with both
schedulers for me, so I don't know what's going on.
