Patch Set 2: Yeah I think there are some fundamental problems with the current parallel startup logic - I don't think it's actually possible to make all cases work with the current approach where all state is receiver-side and there's no additional communication (point-to-point or via the coordinator) to disambiguate hangs and delays.
