Hi,

Could someone please explain quickly why logical clock is used in FastLeaderElection? It looks
to me like the peers can converge on a leader (with highest zxid or server id if zxids are
the same) even without the logical clock. May be I am missing something here, I could not
figure out why logical clock is needed.

Thanks
Raghu
