Yep.

That's quite amazing. If I talk with people about that, it often turns
out that they don't check the integrity of their repos.

Well, hg verify *is* through and fast enough. That's good enough for me.

And being slow is not sufficient to earn my trust.

FWIW, be aware that Mercurial does not do integrity checks on normal
operations, so chances are you will be able to use a repo that fails
verify for quite a while -- without even noticing it.

For example you can remove *some* file X inside .hg/store/data and
continue to add history to that repo without any sign of errors, as long
as the file X isn't used during the operations you do.
