Sven,

I think you have things mixed up. Any modern program lets the operating
system handle the memory. For a program to bypass the OS and try and do the
memory management itself is a sure way to disaster.
The difference is that the older Windows versions don't access anything
above 3GB because they can't address it. It's out of their range. The newer
versions do address it, and in my case with 64bit linux 2^128 bytes is the
theoretical limit (340282366920938463463374607431768211456 which is a LOT).
Having programs go for the "higher" ram addresses is old style DOS
programming.

And as an aside, I do have 8GB RAM and 12GB swap and still manage to have
povray crash with an "out of memory" error :)
