In theory, this should have already been handled by the
YapDatabaseRelationship extension via edges.
However, in practice, there were situations (cause unknown) where

explicitly delete all their interactions, and interactions delete all
their attachments (when applicable).
Also, a class to clean up spurious interactions / attachments
In the process:
