> The  http://www.nabble.com/file/p15994217/UNICAST.java.patch patch to
> UNICAST.java  adds an "immediate_ack" boolean to the UNICAST protocol which
> causes it to return the ACK to the client _before_ processing it.  UNICAST,
> by design, only allows one packet up the stack per sender at any time.  We
> had some flow control issues earlier and this was one of the mechanisms we
> used to alleviate the retransmit cycles where packets would be retransmitted
> 4-5 times even though many had already been received by the received -- just
> not ACK'd.
