> We are not clear enough (and the diagram we do have seems misleading) on 
> _when_ session expirations are generated. In particular the fact that you 
> only get expirations when the client is connected to the cluster, not when 
> disconnected.
> we need to detail:
> 1) when do you get expiration
> 2) what is the sequence of events that the watcher sees, from disco state, to 
> getting the expiration (say the expiration happens when the client is disco, 
> what do you see in the watcher while you are getting reconnected)
> 3) we need to give some examples of how to test this. We should be explicit 
> that "pulling the network cable" on the client will not show expiration since 
> the cliient will not be reconnected.
