i asked you that question because for all this time you seemed to
have been very worked up by the fact that i called the page fault
path as not 'fast'. i thought maybe what caused your nervous reaction
and desperate attempts at trying to justify it was due to some
misunderstanding in wording, but i now see that we probably talked
about the same thing. with the exception that you *still* have not
provided any evidence for your claim. why is that Ingo? do you have
nothing to prove your single cycle 'improvemnt'? (sorry, had a
chuckle again ;).
