Being able to view queue contents in a random-access manner is not very 
compatible with the existing behaviour of RabbitMQ queues where they can 
be paged out to disk (yes, it would be possible, but it would be a huge 
job and not exactly likely to be fast).

You can currently kinda-sorta view contents of queues in the management 
interface - this works behind the scenes by consuming the messages 
without acknowledgement, then requeueing them. This doesn't scale well 
to huge numbers of messages.

It's unclear whether there would be any use for a limited queue browsing 
feature in between these two cases - something that could list messages 
that happen to be in memory but not those that are paged out. 
Conceivably there could be but it's not really top of our list of 
priorities right now.
