----------------------------------------
vishal comment on list:
Nevermind. I am on the wrong track. Flavio's earlier mail did clarify that
the follower received the epoch before restart.
> zookeeper servers should commit the new leader txn to their logs.

> currently the zookeeper followers do not commit the new leader election. This
> will cause problems in a failure scenarios with a follower acking to the same
> leader txn id twice, which might be two different intermittent leaders and
> allowing them to propose two different txn's of the same zxid.
