Yes, I mind.

Chris, you need to get off this hobby horse.  Florent's fix was correct
for the *new* model which has 'getObject' raising (a model you profess
to *like*).

Bugs in the catalog itself, in BTrees, in the CMF, or in third-party
software can leave cruft in the catalog:  robust code *has* to deal with
that problem.
