Calling webSocket.isDataPending gives "operation was attempted on something that is not a socket"

[CoderNate]

OS: Windows

The readSet here is static and in similar places where a SocketSet is used there is a call to readSet.reset() prior to calling readSet.add(...).

arsd/http2.d

Lines 4655 to 4658 in f98b5e1

	public bool isDataPending(Duration timeout = 0.seconds) {
	static SocketSet readSet;
	if(readSet is null)
	readSet = new SocketSet();

I'm seeing that isDataPending works okay for the first WebSocket I create in a session but after I close it and create a new WebSocket one of two things happen:

• Calling isDataPending with a timeout just keeps returning false immediately every time it's called
• I get std.socket.SocketOSException@std\socket.d(3488): Socket select error: An operation was attempted on something that is not a socket.

If I add in a call to readSet.reset() then everything seems to work fine.

that's right i am supposed to reset it, i just barely ever use this function so i didn't test it well. pushed fix up.
