It sounds like they could have supported mmap() easily.  I'd love to see
this kernel, it sounds to me like it was SunOS with nicely done SMP 
support.  The guy that said he'd never seen anything like it before or

I know someone who was friends with one of the kernel guys, haven't talked
to her in years but I'll see if I can find anything.
