Perhaps use of "guard pages" would be as effective and

I believe that's the idea, yes.
It has always seemed odd to me, though, that one can have guard pages at
the low end of a 64-bit space, or at the high end, but not both. Wouldn't
it would be more logical, and more useful, to allow both?!
A different syntax would be needed on the IARV64 macro, of course. But if
you want to guard against overflowing an area, surely it's desirable to be
able to guard at both ends of the area.

Perhaps the thought was an application was likely to use
a downward growing stack or an upward growing stack but
not one that went both ways. Maybe. Just a thought.
