Yeah, I didn't really want to do that, since it takes ~ forever,
but, I did it, and it didn't find a core, so it seems as though
one is not being left behind, and that's a little frustrating.

Well, cycling through them manually and letting each one run for
a couple of seconds didn't unearth anything. I suppose I'll have
to write a script and run a bunch for an extended period of time.

Well, with the exception of it being lock, not clock, I did this,
too, and it does appear that it's dying with a bad pixmap. When
I came in this morning, xlock was not running any longer, and the
ktruss ended with:
X Error of failed request: BadPixmap (invalid Pixmap parameter)

I'll try doing the window trick again for a longer period and see
if that gets me any farther. In the meantime, any other
suggestions on debugging this problem are more than welcome.
Thanks,
Chris
