I'm sorry, I'm lost. You are quoting what I said, that's what I said
said, so what's the point? yes, for the third time, that's what I said
and that's what I meant.

Because, just like the prevailing wisdom in the Linux hackers, they thought
it would be relatively straightforward to get SMP to work. They started at
2, went to 4, etc., etc. Noone ever asked them to go from 1 to 100 in one
shot. It was always incremental.

I recently talked over the approach I have in mind with the architect of
Sun's multithreaded kernel, the guy who started and guided that effort at
Sun. He agreed that if he had thought of my approach he would have done
it that way. We both agreed it was unlikely that anyone would think of
that approach without first having done it the hard way.
