- Actually, you have to go to pure swapping. Then the only things you care about
- are segmentation faults (which you treat as if they were segmentation faults)
- and stack grows (which you handle with a doctored u struct an "stack probes".
-
- The best examples I have seen for this are the 68000 Xenix for Tandy 6000's,
- and the SVR2 for the Amiga 1000 ith a Xebec hard drive (sorry; Xebec only,
- and yes, the Amiga is on Weber's SVR4 source license list).
-
- Virtual memory is pretty mush out of it, as is nearly any form of address
- remapping.
