Yep.  You caught them.  Of course, the release notes do note the shared memory
differences from SVID (Xenix uses "far" pointers - "far" is a Microsoft C
dependent keyword).  They also note on difference in ptrace (it doesn't
fail in one case where it's supposed to) and a few differences in the
termio implementation (QUIT, ERASE and KILL are different, etc.).

OK.

It's amazing we can do anything useful at all with such terribly brain
damaged hardware and software but, still, we perservere.

Xenix, BSD, real SV, SIII, UTS, HP/UX, V7, etc., are all slightly
different.  Everything has bugs.  Brain damage is where you find it.

Memory models and virtual memory, as noted, have little to do with
Xenix.  

What difference does it make, really.
