I don't think asio::io_service::poll() can help you. The only solutions I can suggest I've described before. It isn't
related to Asio - it is related to proactor pattern.

I thought I've already done it :)

It is not a framework. It is more like to be code snippets. Some parts are copies of Asio internals.
