That's what I really enjoy about persons who know everything. They usually
show great intellectual capacity. Use the Pentium's internal cycle-counter
to test something before you state "His code craps all over yours...".

As I stated in the beginning of the conversation, that is now getting way
too tired, test whatever you want with the cycle-counter and the interrupts
OFF so you test only that code. Then repeat your last statement.

Cheers,
