I applied the first 3 of these from V2 already. Looks like the changes
in this round are only t the fourth one so that seems ok.

I didn't apply the fourth one because it touched tools and depends on
patches of mine which can't really go in during the freeze. This would
be a candidate for the new three I mentioned in
<1343057360.5797.59.camel@xxxxxxxxxxxxxxxxxxxxxx> once I start doing
that.
