> If a node sends corrupted gossip, it could set the generation numbers for
> other nodes to arbitrarily large values. This is dangerous since one bad node
> (e.g. with bad memory) could in theory bring down the cluster. Nodes should
> refuse to accept generation numbers that are too far in the future.
