I forgot to mention; Fence calls can only be sent by nodes with quorum.
So a race condition should, as I understand it, be a concern with 2-node
I'm not entirely sure though on how quorum is determined at the time of
partitioning. That is, say you have a three node cluster, and one node
disconnects. I need to verify that it checks to see if it has quorum
before sending a fence call. I expect that is the case though.
