> In Learner.java, txns which comes after the learner has taken the snapshot
> (after NEWLEADER packet) are stored in packetsNotCommitted. The follower has
> special logic to apply these txns at the end of syncWithLeader() method.
> However, the observer will ignore these txns completely, causing data
> inconsistency.
