bpo-31904: fix fifo test cases for VxWorks RTOS by pxinwr · Pull Request #20254 · python/cpython (original) (raw)

LGTM. The updated PR is simple enough and is not too intrusive.

If there are more cases tomorrow, it might be worth it to add an helper function to support.os_helper, but I don't think that it's the case now (it's only used in exactly two functions).
