Thanks for the steer to that FAA URL. I'm still looking through it (but no specific luck so far).
One aspect that does come to mind is LAHSO and all the caveats and cautions attending its use. Obviously if it appears that someone has stuffed up his approach to the extent that he won't be able to land and hold short (but also doesn't look as though he's about to stop trying)..... well that's another case where a prudent step in by the ATCO might just save the day. Two a/c full of fuel and pax (and both in jeopardy) is no time to start debating with yourself whether you have either the right or the rectitude to say the words.
