[openstack-dev] auto-delete in amqp "reply_*" queues in OpenStack

If I run "rabbitmqadmin list queues" on my controller node I see 28 
queues with names of the form "reply_<uuid>".

 From what I've been reading, these queues are supposed to be used for 
the replies to rpc "calls", they're not "durable', and they all have 
auto_delete set to "True".

Given the above, I would have expected that queues with names of that 
form would only exist for in-flight rpc operations, and that subsequent 
listings of the queues would show mostly different ones, but these 28 
seem to be fairly persistent.

Is this expected or do I have something unusual going on?
