> The leader election recipe documentation suggest that to avoid the herd
> effect a client process volunteering for leadership via child znode [i] under
> the leader election path [/leader] must only watch the the SMALLEST znode [j]
> from a different client process such that [j < i].
> This will NOT avoid the herd effect as many clients will end up watching the
> same znode[j] where j is the next-in-sequence number greater than the number
> of the current leader.
> Specifically in Step 3 of the Election procedure here
> http://zookeeper.apache.org/doc/trunk/recipes.html#sc_leaderElection
> This "where j is the SMALLEST sequence number" should be changed to this
> "where j is the LARGEST sequence number"
