> Before this patch UUID update was the same as introduction of a

> would always result in never deleted old UUID.

> The patch on a UUID update marks the old UUID as 'left' member.
> In the best and most common case it guarantees that old UUID will
> be dropped not later than after 2 complete rounds, and marked as
> 'left' everywhere for log(cluster_size) round steps. Even with GC
