totemconfig: Make sure join timeout is less than consensus
The thesis contains this paragraph:
" The Join timeout is shorter than the Consensus timeout and is used to
increase the probability that Join messages from all currently
working processors are received during a single round of consensus."
Empirically I can confirm that making join less than consensus can cause
havoc with a cluster so I think we should enforce this.
