  My/the point is that not all apps *can* be designed that way. It might
be that *if* they can be designed that way, they *must* be designed that
way. But an app developer can not be required to do the impossible.

  Note that I specifically mentioned external data or/and state. If an
app is killed, external data or/and state might/will be lost and the app
*cannot* recover when restarted. Examples of such apps are apps which
depend on data from (internal or external sensors or other data
sources).

  Also note I mentioned in the part you snipped, if all apps/programs
could be designed that way, we wouldn't have paging/swapping on real
computers, but we do. Guess why that is?
