OK, thanks a bunch.

Correction -- it revealed at least two.  See the link I posted earlier in
this thread:

http://www.uwsg.indiana.edu/hypermail/linux/kernel/0808.2/1807.html

Scroll down to the line that starts with "[blog]" for the link. You can see
the discussion I had encouraging him to come here to help us troubleshoot 
if you go to that blog and click "Comments".

I only mention this as a warning, in case it could lead to a lot of extra 
problems for you later.  If you're quite sure that everything is OK, then 
all I can do is thank you again and keep my fingers crossed for you and the
kernel team that nothing bad happens when 2.6.2[67] hit the major distros.

Thanks Yinghai and Ingo (and Peter, Paul, Bill, Mike, Ilpo, Frans, Jesse...
and Andrew, for being the only one to tell me my ISP webmail client was 
breaking threading in everyone's inbox!)

Now leaving LKML...
