> The performance of recovering persistent messages for a queue or a durable consumer is not spectacular in our current implementation for several reasons:
>  (1) Producers are paused while recovery is occuring.
>  (2) All messages for the destination are unmarshalled and sometimes even kept in a list when they are recovered (causes scaleability issues)
> We should provide more of a lazy loading strategy where messages are only loaded based on consumer demand.
