Since there's not going to be any additional data from the client, and
presumably all data on the socket input has been consumed, it would
seem the only "read" event that this could be is a disconnect (which
on Windows is reported as a regular "there's data on the socket").
Feel free to do your homework too, and try to determine what this
event would be about, I can't reproduce everything.

As I said, it's not going to happen that way. The thing calling the
events is a poller, not the input stream, and they are generated when
something happens on the socket, or if there's leftover data waiting.
