Review comment:
My intent on the rotating map was to drop supervisors over time that have
potentially left the cluster.
In my mind, if sending assignments fails every time you talk to a supervisor
regardless of how far back, it means you have a suspicious supervisor. But I'm
fine with tracking the exact times of the events to see if they fall within a
tolerance window if you prefer.
Instead of tracking a count, I could track a list of failure times and drop
the old failures if they're before the tolerance time limit? Would that do
what you desire?
