Yeah, I agree with you.  From and to are unrealistic; it works on
Linux, although I think we use completely the wrong values for from
and to (.text rather than the whole library).  On other targets there
can be multiple distinct ranges.  I'd rather have a "base" of some
sort, but I'm not sure that'd work everywhere either - can you get two
copies of the data segment sharing one copy of the text segment on
some platform?  Probably.
