A proper error code is the right way to do it. It only makes the problem worse if it causes the system to behave poorly so we have to design this feature such that processing it doesn't cause considerable performance/scale problem in the system. One possibility is a backoff algorithm (saw some discussion about it but wasn't sure if it was for this), where we hold off the response if it continues to send requests, in effect choking the client. --Alex
