It was its own thing that the CMU CS department cooked up, and existed
independently of Mach.  The cproc layer, if you'll look, implements a
co-routine non-preemptively scheduled threads library--that works even
on Unix.  This was then ported and layered on top of Mach threads.

I think probably MK82 is where I got it from, but I really can't say
for sure.
