> The current gossip conviction threshold is a bit too low, and can cause hosts
> to 'flap' under heavy load. I suspect that the original author of the
> failure detector implementation originally used both suspect and convict, but
> at some point decided that there was no action to take when a host was
> suspected, or that it was not worth doing. They appear to have
> short-circuited the code to convict on suspect to eliminate this, however
> this caused the suspicion threshold (5) to be used for convicting hosts
> instead of the conviction threshold (8).
