NUMA-aware tcmalloc

For those of you running multi-socket Opteron servers (and eventually, multi-socket Nehalem servers), AMD published a whitepaper last week on their work adapting Google's tcmalloc to be NUMA-aware. The whitepaper includes links to their source code / diffs. It appears to be quite a performance boost in their (very artificial) benchmark. I'll be trying it out soon myself.
