Mother of Lynn Conway, CCL isn't even a descendant of Franz:

https://en.wikipedia.org/wiki/Franz_Lisp#History

That coroutine repo wraps processes (CCL speak for "OS threads") with 
enough plumbing to yield/resume values between coroutines. It's a cute 
trick, but doesn't address the scalability issues one is trying to 
address by implementing coroutines (when you already have OS threads).
