使用python的multiprocessing pool的apply_async()时，经常crash：
Traceback (most recent call last):
File "/usr/lib64/python2.7/threading.py", line 812, in __bootstrap_inner
self.run()
File "/usr/lib64/python2.7/threading.py", line 765, in run
self.__target(*self.__args, **self.__kwargs)
File "/usr/lib64/python2.7/multiprocessing/pool.py", line 342, in _handle_tasks
put(task)
RuntimeError: dictionary changed size during iteration
这个问题在python 2.7.10版本之后被修复：
