Subject2.5.50-mjb2 (scalability / NUMA patchset)
Sorry, previous patch seemed to have some problems on non-NUMA boxen.
This one seems to work fine on a 4x machine at least ... next release
will have more substance ;-)

--------------------------
The patchset contains mainly scalability and NUMA stuff, and
anything else that stops things from irritating me. It's meant
to be pretty stable, not so much a testing ground for new stuff.
I'd be very interested in feedback from other people running
large SMP or NUMA boxes.
