This would be a good article for Macker. How to use UnloadSeg safely. It would
cover
           o  when to do it
           o  what to do in the rest of the code to make sure you don't access
              any globals accessed while their segment is swapped out
           o  how to make sure there will always be space to load a swapped-out
              segment.

Takers? Mail me for submission guidelines.
