------------------------------------
Assignee: Rob Godfrey (was: Robbie Gemmell)
Hi Rob,
Can you review this change please? I havent actually gone so far as removing
scavenge yet, I'd like to rework HouseKeeping a bit to make it much more
frequent before doing that, this is just a little something that needs done
before we could remove it.

> Make the SimpleQueueEntryList Iterator clean the list node structure during
> operation by using the getNextValidEntry() method rather than getNextNode()
> method.
> This will result in the HouseKeeping thread performing cleanup similar to
> that of the scavenge() process, though far less aggressively. In concert with
> the message delivery processes now also using getNextValidEntry() this will
> allow the queue to be more self-cleaning, enabling us to work toward simply
> removing the explicit scavenge() calls which can hinder performance when
> using selectors and/or having vast numbers of messages on a queue.
