Oh, it does. I don't know what you guys are talking about, but asynchronous
I/O is intimately related to tasking.
If you have tasks you normally don't need asynchronous I/O, you do it in a
blocking way.
If you have one task or less tasks than I/O requests pending, you do I/O
asynchronously.
With many simultaneous requests you should go asynchronous because the
number of tasks is limited. An OS can handle far less simultaneous tasks
than simultaneous I/O requests/channels.
For either HD or sockets you could do I/O synchronously (blocking) or
asynchronously (non-blocking).
