// Handle is used to associate with poller's iocp; completer is used to
// inject a completion that will very quickly trigger a callback to the
// completer from an I/O thread. If the callback mechanism is used, there
// can be a RequestCallback set - this carries the callback object through
// from AsynchIO::requestCallback() through to the I/O completion processing.
