It might be a bit off-topic by now, but what is the largest chunk of

The theoretical best is 2GB. In practice, it's less than that, because the
code takes up space, as does the stack, and the data segment.

Ok, that should not be too much as long none of these segments is
placed deliberately in the middle of the big chunk..

But it's fairly close to 2 GB.

It's possible to increase that by a tweak to the OS which takes it up closer
to 3GB, and there are OS calls to get non-flat space (overlays) which can
take you up to (IIRC) 64GB (maybe only 32...not sure now.)

Thank you for this information.

[This is about what I had expected, but there was some discussion
recently (here in my place) where people suggested that's not easy to
get more than a couple of hundred MB of flat address space in NT or XP.
As my own background is rather Unix-ish I finally had to retreat
(although unconvinced) as my only argument was 'They surely would not
waste resources like _that_'... Now I feel a bit better ;-)]
