Dear pytest-dev, on scipy we typically run the test suite using a test script collecting a series of test arguments, then supplies them to `pytest.main()`.
https://github.com/scipy/scipy/blob/master/runtests.py#L307 then https://github.com/scipy/scipy/blob/master/scipy/_lib/_testutils.py#L67 I'm finding that all the tests that involve multiprocessing fail, e.g. ``` def test_pool(): with Pool(2) as p: p.map(math.sin, [1,2,3, 4]) ``` This is on macOS+Python3.8 that uses 'spawn' as a start method. If I run the tests directly using pytest there aren't any issues. Are there any known issues using `pytest.main` with multiprocessing? Andrew
