Calling close() on a closed PeerConnection

I distinctly recall (and have verified with other participants) having a 
conversation around the expected behavior when close() is invoked on a 
closed connection. My recollection is that the outcome of that 
conversation was that close() should be idempotent -- that is, calling 
close() on a closed connection should be a no-op.

The currently published editors' version of the spec, however, contains 
the following text:

> When the |close()| method is invoked, the user agent /MUST/ run the 
> following steps:
>
> 1.
>
>     If the ||RTCPeerConnection|
>     <http://dev.w3.org/2011/webrtc/editor/webrtc.html#idl-def-RTCPeerConnection>|
>     object's |RTCPeerConnection| signalingState
>     <http://dev.w3.org/2011/webrtc/editor/webrtc.html#dom-peerconnection-signaling-state>
>     is |closed|, throw an |InvalidStateError| exception.
>

Based on the conversation we had, this needs to be changed to read: "If 
the RTCPeerConnection object's RTCPeerConnection signalingState is 
closed, abort these steps."
