So if we get at least one KV back we can fall through and not go to the nextscanner(...). The implication is that we'd do an extra RPC per region. Client and server agreeing with absolute certainty to the expected size clearly does not work. was (Author: lhofhansl): As a radical approach, we can fall through out of the while loop in ClientScanner as long as we get _anything_ from the server.
