At the moment you can't - bear in mind that since messages can be shared 
between queues there's not a completely obvious answer to this question 
(which is largely why we haven't tackled it).

It shows how much memory the queue process is consuming - but that 
doesn't include message bodies (which again are shared). Arguably it's 
confusing, but I'm a bit reluctant just to strip it out :-)

Cheers, Simon
