I'm going to have heartbeating as well, but it would also be nice to
have a disconnect notification.  The reason is that to keep network
traffic down, heartbeating has to be done on a relatively long time
horizon (I'm thinking 60 seconds apart) and in financial markets, a
lot can happen over the period of a second or two.
