Nice test. What you thinking? Add this and change TestZooKeeper?

Yes. Let's fix TestZooKeeper first. It is not designed to test this problem it
does not fail stably so also not a good UT for debugging.
And for the rpc, I think we need to find a way to close the
ConnectionImplementation from outside so that all rpc will fail soon.
