I followed it through a little bit and it eventually gets to

newAA->Allocate(sze,ext);

So it IS used then, right? Should it say something more like "The default
value of ext=1000 is almost always appropriate"?

I'm really not trying to nit pick, I just think if we remove the confusion
every time we come across it things will eventually all be clear.
