Irrelevant to the point. Ask the OS how much memory is "free" and it will
include that amount in the response, regardless of the fact that is has it
earmarked. All programs like Norton do is make some very simple system
calls to determine the amount of memory that can possibly be allocated. If
the OS indicated that 61M of memory is in use, if you allocate 4M on a 64M
machine, swapping will occur.
