The wrapping you describe looks a lot like a monad, and your problem
definitely looks like having many (cooperative) threads, some of them needing
to be detached (because they are blocking).
You could have a look at http://ocsigen.org/lwt and adapt it to suit your
needs. Pay attention in particular to the detach() function.
Please, note I might be seeing monads and continuation-passing style
everywhere, since this is my current research topic.
