MaxConcurrentListeners and Remote Transactional Reads from MSMQ

Could it be that MaxConcurrentListereners on a DistributedTxMessageListenerContainer isn't much of use? I have the impression that only one thread at a time can handle a message from the开发者_StackOverflow queue. Maybe it's logical since the message will only be removed from the queue once the transaction is successfull. Or am I wrong here?

Yes, only one thread can receive a particular message from a queue.
Multiple threads can be receiving messages from a queue at any one time, though.
When a message is transactionally received from a queue, it becomes invisible to all other threads until the transaction aborts of commits.
If it aborts then the message reappears in the queue (made visible again); if it commits then the message is physically deleted from the queue.
