But is it really important? All Unixen that I know of handle process
text segments on a page-by-page basis; pages that aren't actually being
touched won't get swapped in. Thus, the unused maps will just sit on
disk, whether they are part of the main executable or a separate file.
I doubt there's any real performance gain to be had by making the maps
dynamically loadable.
