Claus Ibsen commented on CAMEL-4202:
------------------------------------

The reason why the persistent reply to example at the nabble discussion, is 
because Camel will have to use a Dummy value for JMSMessageSelector when there 
is no expected replies to receive. And it thus takes 1 sec. for it to timeout, 
before it can update the JMSMessageSelector with the CorrelationsIDs to receive.

We may try to suspend/resume the message listener container, but we could 
potential end up with some synchronized issue where we would suspend the 
listener, where as in the mean time on another thread a new message is being 
send. And thus we may miss resume the listener. Therefore we end up not pulling 
the message from the AMQ broker.

We should add some documentation / FAQ as the drawbacks of using persistent 
queues.

> The default spring-jms timeout is 1 sec and it impacts the performance.
> Likewise the receiveTimeout should not be set on the reply managers as that
