Hi All,
What is this attribute actually used for?
I see it present on IDataManager but I notice that zope.sqlalchemy's SessionDataManager doesn't have this attribute, with no apparent ill effect.
transaction_manager = zope.interface.Attribute( """The transaction manager (TM) used by this data manager. This is a public attribute, intended for read-only use. The value is an instance of ITransactionManager, typically set by the data manager's constructor. """) This seems to be used only in the tests, I guess it would be useful if you were using multiple transaction managers in a single thread. I've now added it to zope.sqlalchemy's data manager.
