Not sure you can really answer that question because it depends how
you use callbacks, but in my experience with Node you tend to create
closures a lot to use as callbacks, which would probably make them
much more expensive than coroutines. If you managed to use existing
functions callbacks would probably be cheaper/the same. Coroutines
would also help to keep your users sane!
