i want make 1 pool run tasks should follow queue , order.

import multiprocessing import time  def func(msg):    in xrange(3):       print msg    time.sleep(2)  if __name__ == "__main__":     pool = multiprocessing.pool(processes=1)     in xrange(10):        msg = "hello %d" %(i)        pool.apply_async(func, (msg, ))     pool.close()      time.sleep(50);     print "sub-process(es) done."
