I think these are in good shape, but I'd like for Victoria to take a
look at the version on the list here.

We are running these patches at GitHub, and they have definitively
closed the race we were investigating here. But the commit messages
changed slightly when going upstream, so I'd appreciate Victoria's (or
anybody else who is interested) eyes on these.

Thanks,
Taylor
