- Added a new directive used within the scope of an attribute "set" operation
to disable autoflush, in the case that the attribute needs to lazy-load
the "old" value, as in when replacing one-to-one values or some
kinds of many-to-one. A flush at this point otherwise occurs
at the point that the attribute is None and can cause NULL violations.
