I'd be inclined to try turning hyperthreading off. It isn't going to help, and
can certainly make things worse.

again, turn off hyperthreading. If only I could figure out how to
programmatically tell the difference between real and pretend processor
counts ...

I'm not so sure that's still true, though it definitely was the case quite a
while back. Quite a lot of patient, persistent effort has gone into sorting
out the hda drivers, and these days the horrible little thing can perform
ridiculously well for what it is.

Quite possibly true. If the cpu simply can't keep up the pace required, it
simply ain't gonna work. However, silent, catastrophic failure isn't a polite
way for the app to handle the situation. I'm interested in improving that,
especially with regard to "zombies at every patch switch".
