I don't know what's going on there. Can you tell whether
the bad reads are happening during __new__ or during
__dealloc__? Or somewhere else?

One thing to watch out for is what o._destroyed() could
be doing. If it results in the object whose __dealloc__
is executing being touched in any way, bad things could
happen.
