Exception in thread QueueFeederThread (most likely raised during interpreter shutdown)

Hi Guys,
I am using the multiprocessing module. The following code snippet occasionally throws the "Exception in thread QueueFeederThread (most likely raised during interpreter shutdown)" exception.

I searched google for the cause, someone says there are some issues with the multiprocessing.Queue (need do some sleep at where the queue is used).

Could you please shed your light here, what is wrong, how can I use the multiprocess correctly ?

Thanks very much !

The python version is 2.6 and on Win7 x64 OS.

------------------
from multiprocessing import Process,Queue

def listTest(q):
         print q.get()

def queueTest():
        q = Queue()
        q.put([1,2,3,4,5,6])
        p = Process(target=listTest,args=(q,))
        p.start()
        p.join()

if __name__=='__main__':
        queueTest()

Exception in thread QueueFeederThread (most likely raised during interpreter shutdown):
