The "self = nil" doesn't do much gc-wise, as the caller will probably still
have a reference to the same object.  So the "collectgarbage" call can not
yet collect "self"! In the example your "local moo" references the object
troughout the call to delete.  Insert a collectgarbage() just before the
second gcinfo call and see what happens.
