django.contrib.auth.backends.ModelBackend.get_all_permissions() overwrites
the _user_perm_cache as:
{{{
user_obj._perm_cache = self.get_user_permissions(user_obj) # returns the
set that is mutable
user_obj._perm_cache.update(self.get_group_permissions(user_obj)) #
therefore, the set is changed here
}}}
An alternative solution would be:
{{{
user_obj._perm_cache = set()
user_obj._perm_cache.update(self.get_user_permissions(user_obj))
user_obj._perm_cache.update(self.get_group_permissions(user_obj))
}}}
