i'm a bit skeptical that this is going to work out properly. a server
may receive a socket reset even though the client is still alive:
1) client sends a request to a server
2) client is partitioned from the server
3) server starts trying to send response
4) client reconnects to a different server
5) partition heals
6) server gets a reset from client
at step 6 i don't think you want to delete the ephemeral nodes.

Yes that's right. Which network issues can cause the socket to close without

area network issues were more prone to leave dead sockets open rather than vice
versa so I don't know what to look out for.

Subject: Re: closing session on socket close vs waiting for timeout
I think he's saying that if the socket closes because of a crash (i.e. not a
normal zookeeper close request) then the session stays alive until the
session timeout, which is of course true since ZK allows reconnection and
resumption of the session in case of disconnect due to network issues.

That doesn't sound right to me.
Is there a Zookeeper expert in the house?

I foolishly did not investigate the ZK code closely enough and it seems
that closing the socket still waits for the session timeout to remove the
