[issue9207] multiprocessing occasionally spits out exception during shutdown (_handle_workers)

It looks to me as if this issue has already been pretty much sorted out already.  Maybe all it lacks is to be officially closed, but just in case I just wanted to add that I too saw this bug (stock python 2.7, Ubuntu 10.04 64 bit).

My example code was:

#!/usr/bin/env python

import multiprocessing
import os
import time

def f(i):
    print "I am process number",os.getpid(),": i =",i
    time.sleep(10)
    return i*i

pool = multiprocessing.Pool(maxtasksperchild=1)

print pool.map(f, range(10))
