OK, I got it. By "async requests" I mean requests running concurrently, and
I don't have to wait others to process available data. Am I right?

Does asio use POSIX AIO in Linux implementation? I mean librt functions.

How to make some other work while doing i/o operations in single threaded
program?

Thank you.
