Thanks Todd!

One other question though...  does that apply equally to multi-noded
systems like the IBM x3950?  I have a few of those used for test... a
couple are 2 node machines, while one is an 8 node.  That's the
biggest reason for needing NUMA, as anything (Xen or not) running on
multi-noded systems runs better with NUMA :-)
