David Hotham commented on JGRP-1461:
------------------------------------

That does make sense.  I suppose I should go: UFC, MFC, SEQUENCER, GMS.  I'll test it out - please let me know if you see any reason why GMS mustn't be flow-controlled.

> As noted in JGRP-1458, it looks as though SEQUENCER always thinks that sequence numbers must start at zero.  But a member who joins a group after some messages have already been broadcast may never receive sequence number zero.  So, I think, his SeqnoTable will grow indefinitely.
> Note that this one's mostly through code reading.  I think I'm right; but I'm happy to be told otherwise!
> Pull request to follow shortly.
