> 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.
