Mac: Bad file descriptor
Not sure why this has suddenly changed, but tests are now erroring on Mac OSX runners. Worst part is that the process doesn't end after this error, so the CI doesn't fail until it timeouts after 15 minutes.
See test results here (I've also verified on a separate PR, so it's not related to the coverage version bump): https://github.com/aio-libs/aiohttp-devtools/actions/runs/3783707241/jobs/6439936092

Bizarrely, in some cases the tests pass without this error: https://github.com/aio-libs/aiohttp-devtools/actions/runs/3825358870/jobs/6508384673 But, rerunning the failed tests continues to produce the same error result. i.e. In that test run, the 3.8 and 3.10 tests seem to keep failing. But, some have already passed, and another PR has just passed on all checks... Not sure what's going on here.
Taking note that the error comes from py, maybe it's worth replacing that library, as it's not being developed anymore.
@Dreamsorcerer that library is where pytest started (which is why there's still a py.test alias for it).
