Thanks!

One fix: psref_class_create needs to return class before fail1.

One question: can we destroy objects like this?:
  LIST_FOREACH_SAFE(frotz, &frobbotzim.head, frotz_entry, tmp) {
    frotz_destroy(frotz);
  }

If impossible, please teach me how to destroy all objects in a list
safely with psref.
