Each core would then use a cooperative system for handing asynchronous calls among actors. All of the ASIO stuff would happen in yet another real thread which would run the io_service.

I was going to add to that the concept of a 'coop' (perhaps a better name???) for tasks which don't require order, but do require that they are not actually run by two preemptive threads at the same time. This would allow you to write actors that do not need to worry about locking.
boost.task does combine fibers/corroutines (using boost.fiber) with
system threads. It prevents blocking a system thread by an task. It
alows to pin a system thread to a core/cpu too.
