Ready: More ring resizing changes

@jrwest This is ready for review. I'm not sure if this enough information, so please be in touch.
@jrwest Two questions:

1. Did the `fold_preflist_true` setting end up being added? I'm not seeing it in any of my `lib/*.schema` files.
2. Instead of saying no coverage queries, should we still say that they should be minimized? Or are they truly a non-issue?
