bq.      Yes, this can be moved out of the MessageAllocator.   Can you give me 
a little more detail as to how you think the filter & filter type should be 
represented?  I'm thinking that we'd create a filter predicate based on the 
map, and that the move/reroute/purge methods would iterate over the messages 
applying the filter predicate (probably using the return value as the predicate 
to the removeIf).  Does that make sense?

Yes, that makes sense. We may not even need filter type - it would only be 
required if the map structure could take different forms for different filters.
