To my surprise, this patch is broken.
I must not have re-run the python tests locally after writing it :(

The problem is that prevent_dont_repeat returns a cleanup, which is then
left dangling after this patch.

I'm looking into a fix.  Meanwhile I think the rest of the series can
still be considered.
