In WebSphere App Server (WAS), what is the difference between thread pool threads and message listener sessions?

In WebSphere Application Server, what is the difference between the threads in the Thread Pool specified under:

Application servers > server > Message listener service > Thread Pool, threads

and sessions on the Message listener

Application servers > server > Message listener service > Listener Ports > Listener, Maximum sessions/Maximum messages

?

This is very brief explanation, you can find some more details here: http://www14.software.ibm.com/webapp/wsbroker/redirect?version=matt&product=was-nd-mp&topic=ListenerPort

Message listener service > Thread Pool - is the pool available for all listener ports

Maximum sessions - is a maximum number of messages processed concurrently (in separate threads) by given listener port

Maximum messages - is a maximum number of massages processed in one transaction in one thread.

PS. Since WAS v7 listener ports are stabilized and for new applications you should use activation specs.
