I was looking into this issue and realized glBufferData is a special
case, it adds the _NEW_BUFFER_OBJECT flag to dirty states, so we can
check for it and rebind vertex arrays accordingly in that particular
context. This approach may still fail with multiple contexts, because
AFAIK the other contexts won't get that flag.

All the other cases (i.e. what you are proposing) just won't work.
