python 多处理队列对于对象放置是否安全？
Is python multiprocessing Queue safe for object put?
当我在Queue中放入对象时，是否需要创建对象的深拷贝然后放入队列？
如果能保证Object只在一个Thread中处理，这不是问题。但是如果不能，建议使用深拷贝。
如果您将对象放入 Queue 对象，它不会自动执行此操作。

请记住，对象需要能够被 pickle (Multiprocessing Basics)
It usually more useful to be able to spawn a process with arguments to tell it what work to do. Unlike with threading, to pass arguments to a multiprocessing Process the argument must be able to be serialized using pickle. This example passes each worker a number so the output is a little more interesting.
