This gains the QAPI name (good), but loses the address.  The actual
address is rarely useful (when it is, you're deep in Python innards;
good luck, you'll need it).  Except they let me see which objects are
the same, and which are different.  Could that be preserved without
trouble somehow?

Was it my fault?  If yes, I apologize.
