tox -p auto doesn't succeed on my machine, due to this sort of pointless nonsense:

Failure: twisted.internet.utils._UnexpectedErrorOutput: got stderr: b'Traceback (most recent call last):\n  File "/Users/glyph/Projects/Twisted/_trial_temp/twisted.test.test_iutils/ProcessUtilsTests/test_getProcessOutputDefaultPath/lo1gj3tu/temp", line 3, in <module>\n    sys.stdout.write(os.getcwd())\nFileNotFoundError: [Errno 2] No such file or directory\n'
