While investigating bug 1623229, I found that our tests started to intermittently hang. Apparently this happens under certain conditions when forking so I suspected a TSan bug and contacted the developers.
Dmitry from the TSan team has already provided a patch that we can use and it fixes the problems seen in bug 1623229 both locally and on try for me. It might also reduce the rate of bug 1621195 if some of these hangs are caused by the same bug (which is plausible).
I'm preparing a patch for review now.
