Well, based on our experiments last night, recovery is pretty simple:
vacuum the affected table. So it doesn't qualify as a critical problem
in my eyes, although surely it's a "must fix" for 7.2.

I don't think anyone has the energy to put out a 7.1.4. We seem to have
enough trouble getting 7.2 out the door.
