There was a problem hiding this comment.
I expect this will eventually fail because an election involves a couple of round-trips through the transport layer so should sometimes take as much as 4*delayVariabilityMillis (possibly longer, I didn't look for other delays). However I've run over 30,000 iterations of this test without seeing a failure, so maybe I'm misunderstanding or maybe with this delay a bad collision just becomes very unlikely. So empirically this LGTM (except for a couple of nits).
