Deletion of topic on 0.9.0.0 spams this exception

[Scott Reynolds]

>Conditional update of path
>/brokers/topics/messages.events/partitions/0/state with data
{"controller_epoch":2,"leader":492687262,"version":1,"leader_epoch":4,"isr":[492687262]}
and expected version 10 failed due to
org.apache.zookeeper.KeeperException$NoN

I believe this is caused by deleting the topic and THEN shutting down
producers and / or consumers.

Any idea how to cleanly break this cycle of badness ?
