The "3 commit & 4 reveal rounds" is obviously wrong, but it recovers in
the next round.
Also, the "11:31:10.000 [info] sr_state_update: SR: State prepared for new
voting period (2016-05-19 16:00:00)" is correct. But I wonder what would
have happened at 11:00 had tje authority been awake at that time. Would it
have prepared state with the same valid-after time "2016-05-19 16:00:00"?
Is this a bug?
How do we get rounds and valid-after times working correctly when one or
more authorities is voting on the half-hour because they don't have a
recent consensus?
