debugging this thing.
Why doesn't the network boot up quicker?
Why does the VI:0 Precommit for height 1 not come around after round 1 and before round 6?

DBUG[05-04|14:19:36] Send module=p2p channel=22 connection=MConn{162.243.85.60:52630} msg="[Vote VI:0 V:Prevote{1/2 4B634C4301EA#PartSet{T:1 67344F9BB237} 2CFCF951C4D9}]"
Why did blackshadow not send Prevote{1/2} to any other peer?
Did whiteferret not broadcast the Prevote to anyone else?

Blackshadow was locked, so it did:
