<P>
For application servers, <CODE>Connection</CODE> objects provide a special 
 facility 
 for creating a <CODE>ConnectionConsumer</CODE> (optional). The messages it 
 is to consume are 
 specified by a <CODE>Destination</CODE> and a message selector. In addition,
 a <CODE>ConnectionConsumer</CODE> must be given a 
 <CODE>ServerSessionPool</CODE> to use for 
 processing its messages.

 <P>Normally, when traffic is light, a <CODE>ConnectionConsumer</CODE> gets a
 <CODE>ServerSession</CODE> from its pool, loads it with a single message, and
 starts it. As traffic picks up, messages can back up. If this happens, 
 a <CODE>ConnectionConsumer</CODE> can load each <CODE>ServerSession</CODE>
 with more than one 
 message. This reduces the thread context switches and minimizes resource 
 use at the expense of some serialization of message processing.
