As I understand it, there is no "emulation" of UNIX on top of
Mach, rather Mach is a UNIX variant (a cool one) that is compatible
with Berkley UNIX 4.3 (or something; sorry kids, I'm no UNIX fan so
I don't really know the lingo).  What NeXT is doing in their marketing
is trying to prevent the perception that UNIX and Mach are so divergent
that never the twain shall meet (like um, MS-DOS and the MacOS) and that
Mach and UNIX are similar where it counts (so you can run software 
compiled under Berkely UNIX on the CuBE).
