The Knuth book has one *huge* chapter for coroutines. In assembly. The
target has no stack so there is no problem in context switching :P

If you don't need to actively multiprocess they have the *huge*
advantage of not needing synchronization. Alternatives are of course
state machines or continuation passing, for some problem areas are even
better than linear flow....

Mostly because none of the mainstream languages uses them... the most
similar thing to them AFAIK are scheme continuation and LUA threads; and
of course Haskell monads (more or less...) in a horribly different way :D

And, of course, *every* embedded system with a cooperative scheduler at
a yield point!
