Knowing the history of something like this is very helpful, but I'm not sure what you mean by this first paragraph. I think I'm most unclear about the meaning of "The 'threading' approach to asynchronous I/O"? Its opposite ("separating asynchronous I/O from threading") doesn't illuminate it much more. Could you elaborate?
