        >>> ll = get_utility_for_context(IListLookup, context=app)
        >>> print ll.getListForAddress(ml.mailto)
        None

    Send our added event:
        >>> from zope.event import notify
        >>> from zope.app.container.contained import ObjectAddedEvent
        >>> notify(ObjectAddedEvent(ml, app, 'ml'))
        >>> ll.getListForAddress(ml.mailto) == ml

    Change the list and send an event:

        >>> notify(ObjectModifiedEvent(ml))
        >>> ll.getListForAddress(ml.mailto) == ml
        True

    Send a removal event, which should do nothing, as we rely on before
    removal:
        >>> from zope.app.container.contained import ObjectRemovedEvent
        >>> notify(ObjectRemovedEvent(ml, app, 'ml'))
        >>> ll.getListForAddress(ml.mailto) == ml
