Yeah, that makes sense. IIUC setting "force" to false would have the same
effect for the initial round of streaming, but since writePtr/flushPtr will
be set in later rounds, no reply would be guaranteed. That might be good
enough for the tests, but it seems a bit inconsistent. So, your patch is
probably the way to go.
