It was intended for sequential execution (and I had forgotten that I had
purposely placed it after the teardown_environment -- the confusion was
caused by teardown_environment being incomplete). Adding a subtest group
for the preceding bunch would have the debatable consequence of module-
reload reporting a FAIL if something else caused a wakeref leak. My
opinion is to prefer SKIP for external artefacts so that it is clear when
a test failed of its own accord (and so be useful for debugging). It just
so happens that this test was to reproduce the trigger for the external
failures elsewhere and so detect the wakeref leak.
