net.server_epoll: Prevent loop attempting to send last data after close If the connection is closed by the peer, any buffered data is given a last chance to be sent (see f27b9319e0da). If the connection is Really closed, no attempt to write will occur, instead epoll will raise the error flag and :onreadable() will be invoked again, where it will try to :close() again for the same reason, thus looping until the connection somehow gets destroyed. By clearing the _connected flag, the second time it passes :onreadable() it should go directly to :destroy(), breaking the loop. Thanks Link Mauve for reporting
