I don't know, but if the locks are really missing now, I feel like the
first question is "which commit got rid of them?". It's a little hard
to believe that they've never been there and somehow nobody has
noticed.

Then again, maybe we have; see Noah's thread about in-place updates
breaking stuff and some of the surprising discoveries there. But it
seems worth investigating.
