In fact, what I understood is that zope.sqlalchemy, by default, bypasses 
the commit if status is not manually set as 'changed' (see the docstring 
I quoted in my previous mail). The alternative is to build the 
SessionExtension with initial_state == STATUS_INVALIDATED.

My point is that it should be the default for a DA, as it is intended to 
be used mainly by zsql methods which doesn't do nothing to the 
transaction state.

Maybe I wasn't clear but the patch works well with my existing zsql code.
