Happens on line 632 of a current Zope 2.8 checkout:

                if not optimistic:
                    raise TypeError("Savepoints unsupported", datamanager)

'datamanager' is a MultiObjectResourceAdapter for a subclass of
Shared.DC.ZRDB.TM that was registered using the 'register' method of
the Transaction class.
