I don't know where you got that idea. Sun does the same thing and I've
always held it up as a good thing, ``eat what you cook'' type of deal.
The nice thing about doing that is that because of interrupts even a UP
is really an MP, and you don't have to have two different models when
doing SMP.

So I don't hate it. I agree with Ted's comment that it would be nice if
it were possible to have it both ways so as to be able to quantify the
effects, though I don't know how realistic that is.
