Well, RHIDE tells me under DOS it has 70 free virtual megs, 7 free
physical ones. When I go into Windows, it says 1 free virtual and 5 free
physical. So, since I have seen virtual < physical, virtual cannot be
physical PLUS swap unless I have a negative amount of swap space!

On the other hand, I find it very difficult to believe that Windows uses
up 69 megabytes of swap, especially when I set it to only use 20 and on a
different disk than my DJGPP swap file. So why DJGPP only coughs up one
meg of virtual in Windows I don't know. (The 5 physical, I assume, is
because the Windows kernel and locked memory in other apps add up to 2.)
