Yes, you could use stackless, perhaps even Twisted, but I'm not sure if that would work because the requirement for the "reads single-threaded" is the simple wait(...) function call that does a yield (over multiple stack levels down to the function that created the task), something that is only provided by greenlet and stackless to my knowledge.

I don't think we're on the same page then. The way I see it you want a single async IO implementation shared by everything while having a collection of event loops that cooperate "just enough". The async IO itself would likely end up being done in C.
