Mac: Bad file descriptor

Comienza reproduciendo el fallo en un runner de Mac OSX usando los resultados enlazados de GitHub Actions. Sigue la ruta de pytest_forked a través de pytest_forked/init.py y la llamada stdout.close() indicada en py/_process/forkedfunc.py. Se considera terminado cuando las pruebas ya no generan el error de descriptor de archivo no válido y el proceso termina en lugar de esperar al tiempo de espera de CI.

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):
