@anmolnar With respect to the code path above, shouldn't that be blocked on
`syncWithLeader`?

I'm not sure I understand how we don't have this guarantee. My
understanding is that `syncWithLeader` loops until an `UPTODATE` message is
received by the follower. Incoming packets from the leader are read by:
```java
syncWithLeader(newEpochZxid);
QuorumPacket qp = new QuorumPacket();
while (this.isRunning()) {
readPacket(qp);
processPacket(qp);
}
```
In addition, my understanding is that requests are only added to
`CommitProcessor`'s `committedRequests` in `processPacket`. What am I missing?
