Socket + Thread - any working example??

[Vincent]

Hello, guys!
Still fighting with my server example and cannot catch what's wrong. Just simple example:
==========================================
import std.stdio;
import std.socket;
import core.thread;

int main(){
    auto srv = new TcpSocket;
    srv.bind(new InternetAddress(1000));
    srv.listen(10);
    writefln("Listen on port 1000");

    for(Socket cli = srv.accept(); srv.isAlive(); cli = srv.accept()){
        auto t = new ServiceClientThread(cli);
        t.start();
    }

    return 0;
}

class ServiceClientThread : Thread
{
    this(Socket remote){
        cli = remote;
        super(&run);
    }

private:
    Socket cli;

    void run()
    {
        cli.send("hello!\n");
        cli.close();
    }
}
==========================================
After first client connects to the server, it receives (as expected) 'hello!' line, but after this server dies, his output:

Listen on port 1000
std.socket.SocketAcceptException: Unable to accept socket connection

I.e. second call to 'accept' kills server. WHY? Can somebody help me, please? Any working example (in my configuration)?
