OK, so I'm going to hijack this thread (so to speak) because I'm curious 
about what ittook to do that port.

I implemented Concurrent C (C with Ada tasking), first using the 
inter-process mutexes and shared memory in Sequent's Dynix, and then 
using pipes (?!) and no shared memory on BSD. What did your 
implementions look like? Did BSD have threads at that point? Did POSIX 
threads exist on all the systems you ported to?
