Comment (by arlolra):

 > With this patch I got another quick crash on my desktop. Also just after
 the first OnClose, this time a segmentation fault in CGO_Close.

 So now what's happening is that `pc.Destroy()` is being called multiple
 times (3) in the proxy, when the datachannel closes, two of which I
 understand.  I put some guards around that and now my proxy seems to be
 happily serving connections w/o crash.
