Socket server = new TcpSocket();
	server.setOption(SocketOptionLevel.SOCKET, SocketOption.REUSEADDR, true);
	server.bind(new InternetAddress(8000));
	server.listen(8);

	auto set = new SocketSet();
	set.add(server);

	auto sel = Socket.select(set, null, null, msecs(0));
	Socket.select(set, null, null, msecs(0));

(Simplified from loop) On the second select call, fails with:

std.socket.SocketOSException@std\socket.d(3439): Socket select error: An invalid argument was supplied.


The ultimate goal is non-blocking accept calls.  I tried skipping the select() calls entirely and just setting  server.blocking = false;  and  auto client = server.accept();  every loop, but this resulted in accept() returning a non-null Socket object even when no client was connecting, and did not throw an exception to check for wouldHaveBlocked.  When I added the select statement to check for pending connections, the first iteration returns 0 successfully, but the second iteration of the loop failed with the above message.

socket sets usually updated after call to `select()`. you have to recreate the sets before each call.

Ah that works, thanks.
