Yes, that is the guilty commit, although that problem is solved. The 24 process problem is unrelated.

Unfortunately, I haven't been able to reproduce the problem on my Threadripper. I tried Laser, Stockfish 8, and Ethereal 8.28, and they all showed similar amounts of slowdown from 1 -> 8 cores (about 20-30%).

The 24 process problem is very likely specific to that one machine I have, so don't lose any sleep over it.

If you push the fix I will try the new version.
