assertIn()/assertNotIn()? This will give more information in the case of failure.
try:

self.assertIn(str(p12), concurrently_created)

Add "Fixed" at the start, add a period at the end.

In general LGTM, just few minor comments. |

You can also add "Patch by Armin Rigo.".

Since Armin is a core developer and will merge the PR himself this is not necessary.

I updated Misc/NEWS. I will merge and backport once travis CI is completed. |
