Yes...

My first try was to have a single ref-counting for everything, and an attribute for isDurable on the message, but I realized that you could have some of the bindings durable, and some nonDurable. 

So.. you would need to differentiate the two ref-countings. The Durable-ref-counting is used to delete the message from store, while the other one is used to subtract the size of the Address what will happen regardless of the message being durable or not.
