Yes the level 2 interface should be callback driven. And to some agree i
guess the end user have to worry about multiplexeing. At least by declaring
somekind of multiplexor (proactor, reactor) and driving the main
multiplexing loop and letting the user of the library handle threading
issues (apart from the library declaring that the multiplexing primitives
are thread safe).

The asynch part in the sandbox uses boost.function as a completion callback
mechanism. And i the reactor i envision would use boost.function to notify
that a socket is ready.
