[issue15967] Slaves don't seem to clean up their /tmp mess if a step fails.

[Chris Jerdonek]

Chris Jerdonek added the comment:

To follow up on David's comment, the unit tests in the test suite aren't consistent in their treatment of temp directories (e.g. they don't use a common API or code path).  So it may be hard to address this globally short of wiping the entire temp directory (though I could be wrong).

I have a patch in issue 15415 to add a temp_dir() context manager to test.support (and consolidate with script_helper's) that would do such clean-up.  The module already has a temp_cwd(), but that context manager serves two purposes.
