There's actually at least two different tests that sometimes fail: the
other is (

============================ pytest-warning summary
============================
If they are single-CPU-only problems, a potential workaround (warning:
untested) is
@pytest.mark.skipif(len(os.sched_getaffinity(0))==1,"unreliable on
single-CPU systems")
