"""
Rationale for this patch:
Modifications __setstate__ does to self must not cause object to become
registered to its jar (ie, it must have no jar).
Original code breaks this, and this makes it impossible to view, for example,
a former revision of a PythonScript if that revision was written by an old
Zope (ex: 2.12 reading 2.8 PythonScript).
Launchpad bug opened, patch submitted:
https://bugs.launchpad.net/zope2/+bug/735999
