Actually, I'm really surprised by this result, and can't think of a good
explanation even with Serf's ordering ... characteristics.

Paul, I thought the merge process always handled subtrees before their
parents. And their two different editor drives altogether. Is that not the
case? Is it possible that ra_serf is actually overlapping whole editor
drives? If so, that seems (to me) like a big-time problem in that layer. I
still don't think it should block the release, but it's something I'd want
to see investigated.
