I *strongly* agree that that's the single most important piece of information, by far. Though we could and should have several paragraphs about it. We never get around to explaining HOT at all, which is just bizarre, considering its importance. Many very popular user-level talks have mostly just talked about this subject (e.g., a talk from Grant McAlister from a couple of years back comes to mind). -- Peter Geoghegan
