In qio_channel_socket_set_cork(), we call socket_set_cork() but ignore its success/failure return value. This is OK because we are implementing qio_channel_set_cork() here, and that function's API documentation states that the setting is merely a hint. So even if setting TCP_CORK on the underlying socket fails for some reason, this isn't going to be a problem for the caller; correspondingly the qio_channel_set_cork() function has no error return. Add a comment in qio_channel_socket_set_cork() explaining why we don't check for errors.
