 * Stub version of the callback.c functions. Doesn't let anyone
 * _schedule_ a callback (because that would lead them into the false
 * assumption that it would actually happen later on), but permits the
 * other functions without error, on the grounds that it's well
 * defined what they would do if nobody had scheduled any callbacks.
