Would make sense to change "snr" to "ri" or just "r" in this file.

Yes. This whole file could use a cleanup. We don't need a separate raftInterface if raftImpl is the only implementation of it (and there's no way to use an alternative implementation if there were), and it might be simpler to just move all of its methods out to Store or Range directly.

We have been seeing long startup times which disappear spontaneously. During a
restart of the beta cluster, the following goroutine was observed, which suggests
that we were spending a lot of time GCing replicas on startup.
