Is an overlay self modifyig code?
Yes (#2 in my list), but a controlled kind so it doesn't suffer from the
maintainability issues of explicitly modified instructions. But it does require I-cache
management, if the computer has an I-cache. Not all that likely; a machine small enough
that overlays are valuable isn't all that likely to have an I-cache.
