Nedarim 85: Swearing Away the Future

A new mishnah - a woman who makes the things she produces off-limits from her father, brother, in-laws... The husband can revoke the vow. She can't take those same things away from her husband. But what if she made more than the required amount, and that's the part she was making off-limits to her husband? He should still revoke the vow. Especially if they get divorced one day, and that vow would then kick in. Also, the Gemara on this mishnah, and how Shmuel decides the halakhah according to R. Yochanan ben Nori, but then Shmuel seems to contradict his own view elsewhere, with regard to making vows (or consecrating) that which is not yet in effect.
