I wouldn't bother -- as soon as Zope3 comes out, all of this will work
without hacking the Python core.  There is very little chance that such
changes will be accepted by Guido, so it is up to you to decide if this
issue is worth diverging from the stock interpreter.  Esepcially since you
can do the following in the mean time:

class Primary(Persistent):
  def __classinit__(cls):
    # ...

  # ...

# Manually call your own classinit after its definition
# NOTE: This wil go away after Zope3 stops using ExtensionClasses
Primary.__classinit__(Primary)

If you are truely intent on doing this, then the call to __initclass__ be
the final step the end of the ReadyClass function.
