Hi Mike,

I recall that this work was mentioned during the last review in my series.
However, I didn't have time to address it then because I was still working
on the HVO refactoring. I really appreciate you taking this on. Thanks for
your work.

I've reviewed Sashiko's comments as well, and it doesn't look like there are
any major issues. Therefore, feel free to add my ack for this whole series
in your v2 version with the proper fix.
