I have done part of this work with my write deferred swap (I will port
it to test3 ASAP).  The deferred swap write also helps.  It is related
with your question about removing swap_out function, it is related
with the scanning and the several lists setup.

There was a page colouring patch frem somone at DEC^WCompaq, and
another one from David Miller.  The one from Compaq appeared to have
some problems with some workloads (see the comments from Dave Miller,
I think in this list).  I haven't seen the David one, I can't comment
on that.  But I suppose that the integration will be a 2.5 thing
(Wild, wild guess).

Later, Juan.
