> During shutdown, it is possible for an RPC task to outlive the RPC connection
> and segfault when it attempts to signal the engine on timeout.
> In rpc_connection.h, the callback
> {code}
> req->timer().async_wait(std::bind(
> &RpcConnection::HandleRpcTimeout, this, req, _1));
> {code}
> does not retain a reference to shared_this, so the connection can be
> destroyed.
