I think we should discuss what to do in one place, but given the sort of traffic bursts that can arise if you happen to get this wrong, I am still keen to see a couple of sentences here that explain the pathology when a sender has cwnd and no credit, and then suddenly get lots of credit. We see the enormous burst, and it is REALLY not nice if you don't have a pacer to fix it (or figure out the receiver should have sent the credit earlier).
