Does that require explicitly queuing a read or a write operation?

 
Well, I still don't know how Python is implementing things.

The question is, how do *you* think they should be implemented, in such a
way that those claimed limitations would not exist?

Keep in mind that successful IOCP means the completion of an io action
has occurred, or an error has been raised. It could be a new connection,
a buffer was sent, data has been read. That is the C (completion) in
IOCP, see?

In other words, you actually have to have queued I/O operations
outstanding on every connection in order to use IOCP. Dave Cutler
basically reinvented VMS-style programming, with completion callbacks, in
a slightly more message-based form.

This kind of thing does not scale to having thousands of connections open
at once.
