In which case, the update should be convergent, right? I mean, you'd be
setting it to the same value that's already there, so there shouldn't be
any further notifications after the first one, or else I'd say the
notification system is generating spurious notifications.
Or are you saying the problem is that you don't want even *one*
notification in this case?
