but it is broken! the whole point of async i/o servers is that such servers spend most of their time waiting for i/o. and if you need to do some lengthy calculations, you either spawns a "real thread" and commands it to wake you up when it is finished, or asking external server to do the job (and wake you when it is finished). what moving fibers from thread to thread does is bringing in state copying (we want our threads fairly isolated, aren't we? so either copying, or ownership management). the whole thing of cooperative multitasking is to be... cooperative. in several years some Shiny New Async Framework will use "no transferring fibers between worker threads" as Spectacular Invention.
