// 	 Class : QueuedConnectionReader
// Description : This flavor of ConnectionReader will read from its
//               sockets and queue up all of the datagrams read for
//               later receipt by the client code.  This class is
//               useful for client code that doesn't want to deal with
//               threading and is willing to poll for datagrams at its
//               convenience.
