Comment (by yawning):

 There's other things that appear to result in extra threads (nb: libwebrtc
 has the best documentation ever, so this may be totally wrong).

 This: https://github.com/keroserene/go-
 webrtc/blob/master/peerconnection.cc#L60

 Is this:
 https://chromium.googlesource.com/external/webrtc/stable/talk/+/master/app/webrtc/peerconnectionfactory.cc#141

 Which calls this:
 https://chromium.googlesource.com/external/webrtc/stable/talk/+/master/app/webrtc/peerconnectionfactory.cc#167

 Which prevents this:
 https://chromium.googlesource.com/external/webrtc/stable/talk/+/master/app/webrtc/peerconnectionfactory.cc#189

 I'd expect cleanup/deallocation in this: https://github.com/keroserene/go-
 webrtc/blob/master/peerconnection.cc#L185
