So what should the proxy objects do in this case? I guess the idea is
just to invalidate the local property cache so that if someone asks the
proxy for some properties, it goes away and re-fetches them. It strikes
me that it might be nicer to be able to say that a particular property
changed to an unknown value, but I can't see a way to wedge that into an
a{sv}. :)
