This is interesting. I thought asio was using
overlapped io for the blocking calls also.
(If not how, would it be possible then to handle
the pending async calls in the background?)
And when using overlapped for the blocking calls
why wouldn't it be possible then to use the same
Yet another question:
Are you considering to add async file IO to this great
