Why would it unghost the object? If it is already instantiated it
already has all the magic methods that it needs for == , I was in the
impression that the dictionary would only be loaded if any of the
magic methods tried to access a property on the object. Is this to
support overriding methods on objects after instantiation (like
manually messing around with an objects __dict__)?

I tried to read the source of ZODB (to think in what way could it be
ported to pypy) but I didn't get very far.
