Well, it is an absurd interpretation that I would make an implication
that could be refuted by 100's if not 1000's of people who are
looking at the source code.  Sorry, but I did not imply it, and
it is incorrect to use the term Lie, Linus.

Actually, Linus, as I have said, I am not concerned about it
right now, until it impacts significantly, real use of the system.
When it does, we'll make the changes in that part of the system to make
it
faster.  There are so many things to do that impact performance,
I tend to believe that working on this right now would not
be the best thing to do.

Never argued that Linux didn't handle that benchmark well.  The
benchmarks of course, are not in themselves a very accurate
measure of quality.  That is why I am not really worried about
it.

I feel bad that you chose to condemn me for what you thought
was undue criticism.  I have been continually looking for some
information that backs up claims that you have made (on
other threads.)  I am willing to post or mail them to you
for clarification.  (If anyone else would like a copy of the
claim ,just ask.)  I have had no other agendas :-(.
