  18 //   * PepperPortAllocator uses Pepper URLLoader API when creating
  19 //     relay sessions.
  20 //   * PepperPortAllocator resolves STUN DNS names and passes IP
  21 //     addresses to BasicPortAllocator (it uses HostResolverPrivate API
  22 //     for that). This is needed because libjingle's DNS resolution
  23 //     code doesn't work in sandbox.
