This caused us quite some confusion when we started deploying 3.7 applications to Prod two weeks ago, and there were literally zero applicable results on Google for some time, until I looked it up again today and found this PR. Glad to see that it is, as we suspected, a CPython bug, and that there's a fix in the works. Thanks!
