> In the case when a client connection is closed due to socket error instead of
> the client calling close explicitly, it would be nice to enable the session
> associated with that client to time out faster than the negotiated session
> timeout. This would enable a zookeeper ensemble that is acting as a dynamic
> discovery provider to remove ephemeral nodes for crashed clients quickly,
> while allowing for a longer heartbeat-based timeout for java clients that
> need to do long stop-the-world GC.
> I propose doing this by setting the timeout associated with the crashed
> session to "minSessionTimeout".
