IIRC, OS/2 (at least Warp 4) reloads pages from an executable file (such as
.EXE-, .DLL-files) from that
executable file where it is loaded from again (and not from the swap file)
when it's needed again. This is the reason why executable files (.EXE-,
.DLL-files) which are in use are locked by OS/2: to make *sure* that file
can't be changed while it is running, the same is true for those memory pages: 
they are marked as executable code and they are write protected.
