I only got about half the patches, but the ones I did get didn't raise
my hackles.

HOWEVER.

This is very much a "absolutely requires ACKs from Al" series. Al?

Also, because I only got about half the patches, and there's 53 of
them total, I'd really like to see a git branch for something like
this. It makes it easier to review for me, and I suspect it makes it
easier for some of the test robots too.

But again - this needs Al to look at it. Iirc he had some fundamental
concern with the last version - hopefully now fixed, but ...
