has anyone run across an error like this before?

stderr:

we just hit it in CI for the first time. wondering if it’s another mysterious non-atomic locking issue like the error we’ve been chasing @enough-analyst-54434

~impossible to tell. I will note that - don't have the issue at hand - there are now a growing list of folks for whom that issue is solved by the lock style bsd fix. I think it's ~6 to 1 now. Your case of that is truly mysterious. I would love to figure it out.

hmmm ok
