/**

 *  be writing for multithreaded access anyway.
 *
 *  <p>The issue with the messages is that if an implementation is
 *  using a general thread pool then it would be possible for a 
 *  naive implementation to have one thread grab an Envelope from
 *  connection 1's and another grab the next Envelope.  Since an Envelope
 *  may contain several messages, delivering the second thread's messages
 *  before or during the first's would be really confusing and hard
 *  to code for in user code.</p>
