> Due to a timing issue, VERIFY_SUSPECT can kick a good member from the cluster soon after joining.
> A live node currently in the cluster stops responding temporarily (garbage collection, NIC down, etc).
> FD sends up a suspect message to VERIFY_SUSPECT.
> VERIFY_SUSPECT times out and sends up the suspect message.
> Before the node is kicked from the cluster, FD sends up another suspect message to VERIFY_SUSPECT.
> Node is kicked from the cluster.
> Node resumes, is shunned, and rejoins.
> VERIFY_SUSPECT times out and sends up the suspect message.
> Node is kicked from the cluster again.
