Er yes, do you not know what a gigabyte is? its a chunk of physical RAM that
avoids the need for such swapping :-) (I hardly ever see any significant swapping
on my notebook that has 2 gigs, so I can't get excited over the issue. I quite
understand that if I was struggling with a machine with only half a gig, especially
running XP, gcc would be causing considerable grief in some cases.

All machines allow random access to the stack. I have no idea what you are
talking about here or what the relevance of -1(%esp) might be.
