> If the following two conditions are simultaneously met during a split brain:
> a) less than numOwners nodes leave
> b) two clusters are formed having that size
> Then both partitions would be considered as available. E.g. a cluster of 6 nodes with numOwners=4, with a split brain resulting in 3 and 3 nodes partitions. 
> We should add some logic to prevent this situation, e.g. by requiring the remaining partition to have at least numOwners members.
