Comment (by cohosh):

 > The code was a bit unusual. I think CreateAnswer was put into a go
 routine because it's blocking on the ICE negotiation, but we need it to
 complete before calling sendAnswer anyway, so I removed the go routine and
 it appears to be functioning fine. This is not a complete solution (see
 below).

 I'll add that there's a 3 second timeout on CreateAnswer in go-webrtc
