test_tempfile leaked [2, 2, 2] references, sum=6

These leaks are due to 6e5855854a2e: “Implement PEP 412: Key-sharing dictionaries (closes #13903)”. They both occur in tests for tempfile.TemporaryDirectory, although I don't know what is special about that code. I'll investigate further when I have time. Cheers, Mark.
