That's a very good question. And for me to answer in specifics I'd need to
think deeply about the issue, and study examples, neither of which time
currently allows given C++Now is just around the corner.

All I can say right now - and I agree this isn't very helpful - is make it
compatible with opaque third party event loop dispatchers such as Qt's
QCoreApplication and QRunnable. Because Qt's implementation details iare
opaque to external code, if you can meet compatibility with that you'll
probably be compatible with anything Boost.ASIO can come up with, especially
as most of Boost.ASIO is header defined.

I appreciate that isn't very helpful. Thread pool design is hard :(
