I would go the other way and have as few stages as possible and only break 
down the stages if there is a significant pay off. The basic reason is that 
every stage adds overhead and complexity. In most of the seda-style 
request-response apps I would suggest you start with 5 stages (input, 
decoding, logic, encoding, output). Only add more if you need it or are doing 
significant IO during the logic stage.
