I still think this could be a little clearer. Can we pull UDP out into a
separate section. So we would have:

// Private interfaces.
...

// UDPSocketPrivate interface.
// Permissions for UDPSocketPrivate interface will be checked at the...
if (message.type() == PpapiHostMsg_UDPSocketPrivate_Create::ID) {
  return ...
}
