OK, did that too, in case any one else wants to take a look.  I'll pull the note out when landing as it won't mean much in the final commit log.

Instead of landing on a Friday, I think it will be best to wait until at least early next week.  That will give more time for others to comment, and it will make it easier to respond to any immediate issues.  That seems important given the trouble this series had when I tried to land it last time.

Thanks again for your help in moving this along.
