Y'see, I'd look at this as an opportunity to extend C++ Coroutines with 
stackfulness emulation, and that would be exactly the value in a 
standalone Boost library here.

But otherwise I gotta agree with Vinnie here, if you require 
Boost.Context and Boost.ASIO and you only work with those and Chris K 
isn't keen on adding this into Boost.ASIO, the next most logical place 
for something as small as this is Boost.Context surely?
