    My guess is that the collapse extension is modifying the repository without holding a repository lock, which allows TortoiseHg to take a look at it at exactly the wrong time. If verify passes, you can ignore this. Or report it to the collapse extension maintainers and see if they care.

    When I repro it, I'll verify. Looking at the repo when it should be locked sounds like a good fit. I'll follow up with the collapse folks. Thanks!
