Nevermind. I am on the wrong track. Flavio's earlier mail did clarify that
the follower received the epoch before restart.

> 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.
