[issue25695] test___all__ and test_support alter execution environment

[Martin Panter]

Martin Panter added the comment:

This was introduced with revision f8fa7bc837a3. I guess I overlooked the new messages because I run the tests with -Wall, which is affected by Issue 18383.

It seems a bad idea to create a temporary directory when you import the test_support module. I propose this patch to defer creation until the one test that uses it is run.

As for your patch Silent Ghost, I’m not sure. It kind of side-steps the real issue by tweaking a heuristic. Maybe we should keep the heuristic as it is, because it is simpler.
