The only special considerations are with two-node clusters, because
there is no easy way to declare a majority in two node clusters.  So,
there has to be a way to decide which node is "alive" and which one is
"dead" in the case of a network partition.  There are several ways to do

Otherwise, even vs. odd should not matter.  If there are any issues WRT
even vs. odd, it's probably a bug.
