So I have been playing with that part...

While that would be nice, the result is rather ugly and this needs to
generate the same error message in two code paths. So I have chewed
things in such a way that one failure found makes the whole rewind to
just fail, and allows retries to work. The attached has a test as well
as documentation.
Thoughts?

That's mentioned in the docs of the attached.
