what happens if there's a thread switch, to another thread using the local object, here? between patching dict and accessing dict
return object.getattribute(self, name)
def setattr(self, name, value): patch(self) return object.setattr(self, name, value) def delattr(self, name): patch(self) return object.delattr(self, name) def del(self): key = object.getattribute(self, 'local_key') for thread in enumerate(): if key in thread.dict: del thread.dict[key] Any objections? Any more tricks up your sleeve Armin? :) Jim -- Jim Fulton mailto:jim at zope.com Python Powered! CTO (540) 361-1714 http://www.python.org Zope Corporation http://www.zope.com http://www.zope.org
