I believe in Christian's setup consumers may operate very slowly, or not 
connect at all for a very long time. Meanwhile messages are piling up at 
the server, which will eventually hit hard resource limits, namely disk 
space. So a mechanism is needed for messages to be evicted *in the 
absence of cooperating consumers*.
