Why would you want the session to expire if all the servers are down (which
should not happen unless you kill all the nodes or the datacenter is down) ?
A more likely case is that the client port on the switch dies and the
client is partitioned from the servers...

A client will disconnect from a server in the ensemble and attempt
reconnect to another server in the ensemble if it doesn't hear from the
server w/in 2/3 of the specified session timeout.
OK... I got that part. The issue I'm running into now though is that my
sessions aren't actually timing out when I shutdown all servers in an
ensemble.
One solution/hack would be to record how long you've been disconnected and
assume that your session has been expired.
