Re: [streams] Garbage collection (#252)

Oh, very interesting. Quoting from https://html.spec.whatwg.org/multipage/comms.html#garbage-collection-3:

> If a WebSocket object is garbage collected while its connection is still open, the user agent must start the WebSocket closing handshake, with no status code for the Close message.

In streams terms, this would be equivalent to automatically calling `webSocket.readable.cancel()` + `webSocket.writable.abort()` upon GC of `webSocket`. You're totally right that this is not doable in JS as it stands. How sad.

I don't really know what to say :(
