I ran overlayed programs all the time.  My Ultrix-11 was a heavily
overlayed kernel to have room for networking. No big deal.

I do remember building overlayed progrmas for MS-DOS, using interrupt
0x21 function 0x4B03, and files linked into separate .OVL files. One
could have code and data far greater than the actual memory limits,
very useful back in the bad old days before the 386 came along and gave
us 32bit flat mode and most usefully "voodoo" mode that allowed MSDOS
to run 32 bit programs and not need rebooting.
