I need people running Mac OS to test some patches before releasing them
in 2.0rc2 (which is likely delayed to Monday).

Just build this tarball, run lstopo, and report any difference with
older lstopo outputs:


Hopefully, things won't change on most machines. On laptops without
hyperthreading, you should now see the right number of cores (instead of
N/2 dual-thread cores).

If anybody has a dual-socket machine, I am interesting in seeing whether
we properly detect the NUMA nodes. My only test case so far is a
dual-Nehalem machine which reports a single NUMA node. Not sure if the
BIOS is set to NUMA interleaving or if Mac OS reports wrong information
in sysctl.
