AIUI, that involves a circular reference.  If anybody wants to try some 
benchmarking, compare it with the following:


dynamicModule = "__dynamic__"

def setDynamicClass(object):
  if object.__class__.__module__ != dynamicModule:
    class klass(object.__class__):
      """dynamic class for hacking"""
    klass.__name__ = object.__class__.__name__
    klass.__module__ = dynamicModule
    object.__class__ = klass

def addMethod(object, function):
  setDynamicClass(object)
  setattr(object.__class__, function.__name__, function)
