在给定的multiprocessing.connection.Listener.accept（）给定时间后引发TimeOutError

Question

我试图打断multiprocessing.connection.Listener.accept()，但到目前为止还没有成功。因为它没有提供timeout参数，我想也许我可以使用socket.setdefaulttimeout()来打断它，正如帖子中所建议我再也找不到了，这里就是SO。

这没用。然后我尝试在close()对象上调用Listener()。根据this post's answer，这应该有效。

然而，似乎这些对象不能与通常的socket相关的解决方案一起发挥作用。

我可以确认Listener被Timer对象按预期关闭，但accept()呼叫不会中断。

代码：

import socket
import os

from threading import Thread, Event, Timer

    behaves like a Queue as well as a Thread.

                self.feed_data(client)
            except (TimeoutError, socket.timeout):

我意识到我的问题是这个question的重复 - 然而，它已经差不多一年了，甚至没有收到评论。另外，我使用Unix Domain Sockets，而不是链接帖子的TCP连接。
