Yup, that's pretty much the subset of the io_service API I had in mind.

Yes. Many applications and even frameworks want to own the main loop.
By default, Asio is one of them. Fortunately it does have these
Since you propose a Boost library, it would be a valuable exercise to
consider how best to integrate your framework with Asio -- especially
considering that something very like Asio is well on its way to
becoming part of the C++ Standard.
