>
> RPC handlers currently do not return until the RPC call completes and
> response is sent, or a partially sent response has been queued for the
> responder. It would be useful for a proxy method to notify the handler to
> not yet the send the call's response.
> An potential use case is a namespace handler in the NN might want to return
> before the edit log is synced so it can service more requests and allow
> increased batching of edits per sync. Background syncing could later trigger
> the sending of the call response to the client.
