Comment (by robertwb):
I think metaclasses are only supported for non-cdef classes. (This should
probably be a compile-time error rather than silently ignoring it.)
There's also sage.structure.factory.UniqueFactory. It may also be worth
holding a strong reference to the last N (for some small N) parents
created to avoid creating the same one over and over.
In any case, this isn't a regression, so I'd be happy to get this fix in
and post a follow-up ticket to ensure uniqueness.
