Socket: Detect connection close

[nrgyzer]

Hi guys,

I'm experimenting with sockets and having trouble to detect when 
the remote side closes the connection. Here's my code:

// Client:
module client;

import std.socket;

void main()
{
        TcpSocket s = new TcpSocket();
        s.connect(new InternetAddress("localhost", 8080));
        SocketStream ss = new SocketStream(s);

        for (int i= 0; i < 10; i++)
        {
                ss.write(1);
                ss.flush();
        }
        ss.socket.shutdown(SocketShutdown.BOTH);
        ss.close();
}

// Server:
module server;

import std.sdio;
import std.socket;

void main()
{

        TcpSocket s = new TcpSocket(AddressFamily.INET);
        s.bind(new InternetAddress("localhost", 8080));
        s.blocking(false);
        s.listen(0);

        while(1)
        {
                try {
                        Socket requestSocket = oSocket.accept();
                        RequestThread rt = new RequestThread(requestSocket);
                        rt.start();
                }
                catch (SocketAcceptException e)
                {
                        Thread.yield();
                }
        }

        s.socket.shutdown(SocketShutdown.BOTH);
        s.close();

}

class RequestThread : Thread
{
        private {
                __gshared Socket s;

                void run()
                {
                        ubyte[1] buffer;
                        while(s.isAlive)
                        {
                                s.receive(buffer);
                                writeln("receiving");
                        }
                        writeln("client closed connection");
                }

        }

        public this(Socket socket)
        {
                super(&run);
                s = socket;
        }
}

I know... dirty (really) dirty code, but it works , except that 
I'm in an endless loop and my server always prints "receiving". I 
never see "client closed connection" although the client sends 
only 10 int values. It seems that "s.isAlive" is always true. How 
can I detect when the client closes the connection (or how can I 
detect if the connection is broken)?

Thanks for any suggestions or ideas!
