Ah! I succeeded to hack a tool to bisect -m test -R 3:3 failure (issue bpo-29512, I will publish it later, right now it's too hackish), so I found a first guilty of failure on the Gentoo Refleak failure.
Maybe it's related to recent Eric Snow's work. Maybe not. I didn't dig the bug yet.

I tagged this issue as easy. I consider that it's a good exercice for new contributors. Core developers: please let new contributors try to fix it since this issue is not critical, try to explain how to fix it rather than writing the fix ;-)
