I am (As I get time) working on adding some NUMA awareness to ULE.
Mostly, this effort isn`t focused on real NUMA installations, but on
optimizing FreeBSD for use with Opterons where there is a penalty for
accessing remote memory (Attached to another socket). After discussing
it with some people though.... it appears to be the same project, just
different weighting in memory allocation and scheduling
