在Windows上新的Python期货模块只是我或者是严重错误的

Python 3.2 (r32:88445,Feb 20 2011,21:29:02) [MSC v.1500 32 bit (Intel)] on win32 Type "help","copyright","credits" or "license" for more information.  

>>> from concurrent import futures  
>>> executor = futures.ProcessPoolExecutor()  
>>> def pio(x):  
...     print("I AM HERE")  
...     return True  
...  
>>> fut = executor.submit(pio,5)  
>>> Process Process-1:  
Traceback (most recent call last):

>>> fut.running()
True

这对我来说看起来有些不对劲.救命 ！
