初始化驱动程序时Selenium连接超时

Question

我写了一个Django（版本1.3，遗憾地）管理命令，用Selenium连接到BrowserStack，我将用于运行集成测试。 （我必须编写一个自定义管理命令来解决我们在这个站点中使用AskBot的事实，它以一些有趣的方式弄乱了Django测试框架;否则我只是使用测试框架。）

脚本的要点在这里https://gist.github.com/cellofellow/7491221 。 这是一个早期脚本的端口，只是在没有任何Django上下文的情况下直接运行unittest。

会发生什么事情，当我跑步时，我会得到一个跟踪：

./manage.py browserstack signup

Browser Version: 10.0
Operating System: Windows

在BrowserStack中启动一个实例但是因为接下来发生的任何事情无法连接，它只运行一分钟左右然后退出。

它移植的脚本没有这个问题。 可能是什么造成的？

事实证明我只需要设置socket.setdefaulttimeout(60)在这个代码库中有几十次对socket.setdefaulttimeout的调用，包括依赖项和我们自己的代码，所以谁知道实际设置的是什么。
