Thanks for the report. I've never actually encountered this error. Just
lucky, I guess.

It’s a race condition. The machine I run it on has 6 cores and HT, so I run it 
with a `make -j 12`, and even then, it’s not consistently reproducible.

Sure. I run make -j 4 at a minimum, make -j 8 sometimes, and I've never
seen it. Not very reproducible.
