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!
