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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
