I'm not sure what that would even look like. The exchange would have to 
contain a priority queue in order to do this, but how can a priority 
queue really exist there since exchanges are meant to be (conceptually) 
stateless? At what point does the exchange deliver messages?

Supposing we experience a pause here - can the exchange forward these 
messages on to the queue in that order? If not, how long is it supposed 
to wait for msg3?

(Or is that not what you're asking?)
