Sounds good. I don't think we'll spend more than 5-10 minutes
on the latency thing, probably less than that.

I believe that problem is complex enough to warrant a 30
minute discussion. Even if we do not come up with solutions,
it would be a good start if we could all agree on the problem.
Things this complex often end up getting shot down later, not
because people do not agree on the solution, but because people
do not agree on the PROBLEM (and the patches in question only
solve a subset of the problem).
I would be willing to lead the NUMA scheduling and memory
allocation discussion.
