    it was not what was intended originally (the domains were supposed to be
    completely independent beasts), however I can see that this is confusing
    and even undesired, so I am ok with the change.
    Ideally we get a way to have an async domain opt out of the global sync,
    but until I get an actual user of that into mainline, don't worry about it.
