[3.8] [3.7] test_mkfifo_dir_fd triggers segfaults on macOS CI #102306
Description
A PR upgrading pip's wheel on 3.8 (which shouldn't really affect the test_mkfifo_dir_fd) triggered a segfault on the macOS test run.

Looking through the issue tracker, I don't see that failure mode reported as is and I'm noting it here mostly since I'm not sure if it's in any way related to this ongoing thing or if it should be a separate issue. It doesn't seem like it is, but I've not followed the failure discussions here closely to know for sure. 😅

We've also seen this happen on certain other runs as well since, including a re-run on the aforementioned PR.
