you're obviously running something pre ec44c8bd6c, judging by PathLocks::lockPaths appearing in the traces above despite this function having been gone for over a month. those versions did have locking bugs that would cause things to get stuck like this (eg #613). next time please fill in the report fully, okay?

has this happened any more since? we haven't seen any deadlocks in a long time and would thus consider this problem to be solved
