Review Comment:
We could add a safety margin of one or two so during coalescing it doesn’t
fail, but I think it makes sense to enforce some kind of bounds checking. I
think it will complicate things a bit though as we also need to handle the
exceptional situation of a too long chain. in general I agree.
