However, the connections are generally reliable and I'm pumping many messages/second through the federation before shutting the brokers down. (Xref my other thread about extraneous federation exchange traffic.)

Hmn, I wonder if this is somehow linked to the 'leaky bindings' mentioned in that thread - I doubt it somehow. Are you in control of the network - can we be sure that packets aren't being dropped for some reason or another? As Simon intimated, the behaviour you're seeing appears to be client sockets hanging around during shutdown until a timeout is triggered. Perhaps we're not seeing the expected FIN - I'm attempting to reproduce this at the moment.
