Why do you say that single process is limited to 2 Gig? I believe that on
windows a single process can run with to 32 bits addressed or 4 Gig of
space. I have run R with over 2 Gig of memory.
Why would python be limited to 2 Gig (including overhead)? I don't see that
python should be any different.
