Disconnect from JS does not work

[kodlian]

RocketSockem works perfectly for receiving and sending messages from JavaScript client. But I'm not able to disconnect the JS Client on Safari - on Chrome it takes a very long time to be disconnected.

     // Server
    _server = [[RSMServer alloc] init];

    _server.port = 19487;
    _server.interface = @"localhost";

    [_server.webSockets subscribeNext:^(RSMWebSocket *socket) {
        [socket.messages subscribeNext:^(id x) {
            [socket sendMessage:x];
        }];
    }];
    [_server start:nil];

    // Client
    ws = new WebSocket("ws://localhost:19487");
    ...
    ws.close();
