More than one instance of Chrome locks up LiveServerTestCase

[Luke Plant]

Example code:

from django.test import LiveServerTestCase
from selenium import webdriver

class TestChrome(LiveServerTestCase):

    def test(self):
        url = self.live_server_url
        driver1 = webdriver.Chrome()
        driver1.get(url)
        driver1.get(url)  # This 2nd get seems to be needed to trigger the bug
        
        driver2 = webdriver.Chrome()
        driver2.get(url)

        driver1.quit()
        driver2.quit()

This code was added to tests.py in an otherwise blank project (no views or anything necessary), and run using ./manage.py test

Result: the second Chrome window simply hangs trying to load the URL.

Tested with:

• Django 1.10.4
• Selenium 2.53.6
• Chrome 55.0.2883.87 (Official Build) (64-bit)
• ChromeDriver 2.27.440175 (9bc1d90b8bfa4dd181fbbf769a5eb5e575574320)

Upgrading to Selenium 3 is not an option - so many things are broken (like any half-decent Firefox support, as far as I can tell).

I'm guessing this might be to do with Chrome holding open connections. If I close the first Chrome window, the second one then succeeds to load the page.

#20238 is open to support multiple open connections in LiveServerTestCase. Can we consider this a duplicate of that?

That sounds good - thanks (assuming my guess about the cause is correct).
