I guess the right thing would be to purge the outsanding replies after a timeout. If that were an issue, however, we would have seen it already as the exact code exists in our codebase - take a look at HandleErrorVoid and handle_structured_error in MirConnection. So with the march towards CapnProto, I don't think it's big enough a concern to warrant spending effort at this point.
