So I’d like to implement something with this, or a similar, interface:
isn't it better to provide os-independent interface to semaphores? named semaphores both on windows and unix may be used to implement functionality you required and it's a more natural way there is useful article [1] which describes both windows and unix way to threads/events/semaphores/mutexes. how about implementing lightweight library which abstracts over these differences? OTOH, i've just recalled one C++ library which does exactly this job [2]. may be providing Haskell interface for it will be a better idea?
