[TUHS] Split addressing (I/D) space (inspired by the death of the python... thread)

[Steve Simon]

not quite split i and d but i do have a memory of some code which could run in three parts as overlays.

this could have been through exec’ing the next overlay with an appropriate argv and a pipe or file of data, or, perhaps there was some kernel support for overlays in early unix.

anyone seen evidence of this?

sadly i cannot remember where i saw it, i want to say it was a versatex printer driver but i am pretty sure that is rubbish.
