> Reclaim memory when page cursor completes.
> There are two hash set used to hold page position for acks and removed 
> message references. Both are cleared when page cursor is marked done. While 
> clear a hash set does not reclaim memory the under line hash map claimed 
> before.
> Things go bad when you have an address with many bindings and one of them 
> consumes slowly.
