Selenium connection time out when initializing driver

Question

I've written a Django (version 1.3, sadly) management command to connect to BrowserStack with Selenium and am going to be using to run integration tests. (I've had to write a custom management command to get around the fact that we use AskBot within this site and it messes up the Django testing framework in some funny ways; otherwise I would simply use the testing framework.)

Gist of the script is here https://gist.github.com/cellofellow/7491221 . This is a port of an earlier script that just ran unittest directly without any Django context.

What happens is that when ran, I get a traceback like so:

./manage.py browserstack signup
Browser: IE
Browser Version: 10.0
Operating System: Windows
OS Version: 7

In BrowserStack an instance is started but because whatever happens next can't connect, it simply runs for a minute or so and then exits.

The script it was ported from didn't have this problem. What may be causing it?

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。
