But the problem isn't whether we know both the old and new ones. The problem is that we can only abort before the fork commit point and the "old" one may change between the abort point and post-commit point so we need to trycharge the old one at the possible abort point, remember to which css it got charged and then check whether the association has changed inbetween at the post commit point and readjust if so.
