Re: 32-bit programs on Windows x64

What part of "virtual memory is not physical memory" are you missing.  I've said this
eight or ten or a dozen times, VIRTUAL MEMORY IS NOT PHYSICAL MEMORY.  

Not only does my process require 4.0 GB of RAM, it is also time
critical. If there is any swapping to and from VM, then the current
project becomes infeasible. I must know how much actual RAM is
available to my process, even though this actual RAM will be mapped to
VM. If three is any swapping to and from disk, the current project
becomes infeasible, my maximum response time is 1/10 second.
