This was requested first by someone else, but to my knowledge, no clear
solution has been found:

I need routines, Public domain or otherwise, for either Microsoft C 5.0
or Lattice C 3.2 that will swap my program and data out to disk when I 
call the system() function, so that I will have more memory available 
for the new program to run. 

 - The amount of memory required by the new program should be specifiable,
   which means the swapper must check the memory available and only swap
   if necessary. 
 - It must make sure that memory to which interrupt vectors point is
   not swapped. (there may be no easy way to do this.)
 - It must make sure it doesn't swap itself out, since it has to swap 
   back in when the other program finishes. 

I know it's possible, because SmallTalk/V and Microsoft Windows do it, but
I don't want to be bound by a license agreement that must be passed on to
my 100 or so users. 

Thanks in advance,
