[Zope] session invalidate - using python

[Chris McDonough]

No.  By doing data.invalidate(), you've invalidated the data object
(which means it will eventually be removed from the session data
container), but that won't magically turn it in to the None object.

It makes sense that on each call you're getting a new data object as
you're invalidating the old one.

getSessionData returns a session data object associated with the
current browser id.  The "create=0" argument doesn't mean "dont
create a session data object", it means "don't create a session data
object unless there is a current browser id".  Since there is a
current browser id, a session data object is returned instead of
None.
