> SnapshotCache cleanup might be unnecessarily strict. 
> The cleanup throws an `IllegalStateException` when it finds stale entries in `pendingEvictionQueue` for snapshots that have already been removed from dbMap (say when SnapshotPurge invalidates the entry).
> It might be better for cleanup to log the stale entry proceed without failing since this is not a correctness bug.
> Also, invalidate should also remove the entry from `pendingEvictionQueue` to be more consistent with bookkeeping.
