LiveServerTestCase in 1.10.4 doesnt close server ports properly

[Mike Hibbert]

I get the following error when using LiveServerTestCase along with lettuce:

Traceback (most recent call last):
  File "./manage.py", line 22, in <module>

To reproduce the bug I've attached my Django project that can be run.

The error occurs when you try to run the tests. The first time through it works fine but if you try and run the tests again with about 1 - 2mins it will give the error above.

When I downgrade to 1.9.4 this works fine without the error.

Here's my code to reproduce the bug, the upload restrictions stopped me adding an attachment but you can see my test case here ​​https://www.dropbox.com/s/18uy88gz6frjyeg/bdd_app.tar.gz?dl=0
