At one point, the linker would just willy-nilly put things back to back.
For example, text might end at 0x1231, and data would then begin at 0x1232.
When paging, you do *not* want to use old data.  Therefore, if you want to
page directly from disk, you arrange things such that everything is in a
decent arrangement (which is what your kernel would do for you when it
swapped pages to the swap device).

At least, that's how I understand it.
