I started to review this series on top of [1], but I didn't get
much past here because of the build failure. I guess there will be at
least one more small change needed because of the alternative way I
ended up doing "remove all properties".  I find

% git rebase -i -x "make test"

an effective way of making sure things are in a good state after every
patch. At least it's effective when I remember to do it; just before
writing this, I discovered a rebasing error in [1] that caused a similar
build failure.
