Hi Martin, I re-laned it last time 10 days ago: b332134921b4 Mon, 13 Dec 2021 12:48:34 +0100 tsan: new runtime (v3) at this point it wasn't yet reverted... Few more issues were fixed and it now survived testing in Chromium. I hope it won't be reverted anymore... but can't promise (it's not me who revert it :)) I would say if we wait a few more days maybe, it's reasonably safe to assume it sticks.
