> Mutation tracking needs a background process that attempts to reconcile
> missing mutations among replicas. To handle unusual network failures,
> replicas should be able to learn about the reconciliation states of peers it
> can't talk to via other peers & coordinators. The replica background process
> should prefer the coordinator process does as much work as possible, since it
> knows which nodes acked which writes, with the background process only doing
> work when it can't reach a coordinator and/or a coordinator can't reach a
> peer.
