std.socket - problems closing socket

[simendsjo]

Not sure if this is a problem with std.socket, nginx or my knowledge of 
sockets. I'm pretty sure it's the last one.

I'm experimenting with fastcgi on nginx, and the socket stays in 
TIME_WAIT even after I call
   socket.shutdown(SocketShutdown.BOTH);
   socket.close();
