The problem is that for the queues you'll have to be contiguous anyway- 
at least they can be separate. I'm mulling over splitting the cdmat into 
3 separate spaces- request queue (64K max), response queue (64K max) and 
'misc' queue (probably also 64k max).

I'm going to check in the current fix since that will probably work for now.
