Actually I hadn't noticed it initially but while testing threads=1 it did pin
two threads to cores 0/1, 10/11, and 20/21 which should be a physical and SMT
for each physical core. The penalties I've seen on Windows amounted to a few
percent when binding some CPU hungry thread to a physical vs SMT (ie core 0 vs
core 1) with no load on the other in the pair when testing. I'll test that
separately on FreeBSD at some point to see if the same penalty applies.
