In Plone, how do I fix Archetypes content that is missing the cmf_uid() annotation?

I'm using Plone 4.3 with relstorage and I've somehow managed to lose the cmf_uid annotation on some of my content objects. This prevents collective.iterate from being able to check in content. Is there an easy way to have Plone walk through the database and re-add cmf_uid where it is missing? Already tried collective.catalogcleanup to no avail.

Here is a script that searches the portal (passed as context) for any Document that has a non-unique cmf_uid. Many of these documents actually have no cmf_uid but the indexed cmf_uid actually comes from the parent folder via Acquisition. Since the manifestation of the problem was that plone.app.iterate was unable to check in Document, the script adds a unique cmf_uid to just the Document types that appear to have non-unique cmf_uid but actually have no cmf_uid.

Although this adds cmf_uid to all Document, it would probably be sufficient to only add the attribute to documents currently being edited in checkouts.
