Ah, figured it out. You have to have ZClasses created that don't derive
from the Persistent base classes - the ZClass interface now includes this.

Unfortunately the fix to ZClass.py:1.37 to copy manage_options from the
base class fails if you create a ZClass that derives from nothing at all.
I wrapped the copy operation in an if zope_object: test (not sure that this
is the best approach, a better one might be to test for manage_options
being there at all) and it's happier...
