Message ordering protocol for TCP unicasts
------------------------------------------

                 Key: JGRP-717
                 URL: http://jira.jboss.com/jira/browse/JGRP-717
             Project: JGroups
          Issue Type: Feature Request
            Reporter: Brian Stansberry
         Assigned To: Bela Ban


With the introduction of a thread pool in the TCP protocol, the ability to relying on TCP/IP to guarantee ordering of unicast messages is lost. See JGRP-716.  Solution is to add UNICAST to TCP-based stacks that use a thread pool.  This is not ideal since UNICAST adds overhead for reliable transmission (sending ACKs, retaining sent messages for retransmission) and this overhead is unnecessary with TCP.  Request is for a protocol with the message ordering functionality of UNICAST but without the reliable transmission features.
