Patrick Hunt commented on ZOOKEEPER-922:

Hi Camille, the patch has to be created from the top most directory ("trunk") 
for hudson to apply the patch correctly, please see:

(basically checkout trunk, make changes, do "svn diff" at the toplevel)

> 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".
