Do you use the word 'stack' as synonym of LIFO, or for something else?

If the former, then I don't understand how it could be true.
LIFO is one of those structures for which PAE windowing should work very well. Even when, for some reason, you can't map the hot spot into your address space, with LIFO you always can fill/spill into paging pool. For correctly chosen low/high water marks, the overhead of fill/spill process should be very small.

It's seems, here you are describing the situation in which you were running out physical memory rather than out of address space.
