The more I think I think about it, the more I wonder whether Solaris did things right - having a special operation to "cross the boundary". I suspect Solaris did it that way because it's a hell of a lot easier to do it like that, but regardless, it would solve the issue of real directories having both real children _and_ the "extra streams".
