At the moment attaching/detaching queues is an unpriveledged operation.

Shouldn't we worry that an application can cause large
allocations, and provide a way to limit these?

David, could you comment on this please?

I don't want arbitrary limits imposed.

Where does this "application" run?  If it's in the host, then who
cares?  If they suck up all of their available memory with queue
resources, it's their problem.
