I didn't refer to data only:  Modern DPMI managers swap both code and
data to disk if there is not enough physical memory.  On such a platform
just forget about overlays and such:  You always have them automatically.
(This holds for Borland Pascal 7.0 in protected mode, too.)

Yes.  Under DOS, DJGPP and EMX swap memory to disk unless you disable it.
When EMX runs under OS/2, the OS does the swapping.
