The Elephant MOP overloads class objects to store a variety of data. The MOP only guarantees to call finalize-inheritance at the latest when an instance is created, so if you call get-instances-by-class, the Elephant MOP has to make sure to call finalize-inheritance.
Sounds like we need to do the same thing during persistent class initialization or change the way in which the Elephant MOP creates new classes (so finalization isn't needed until the first instance creation time or other operation over the classes).
