#26011: allow_reuse_address = 1 on WSGIServer can cause random test failures in
LiveServerTestCase on Windows

-----------------------------------+--------------------
Windows happily allows a process to steal another process's address when
`SO_REUSEADDR` is set. This can cause requests to go to the wrong
`LiveServerThread`, and cause random test failures, such as
http://djangoci.com/job/pull-requests-windows/886/. I can't reproduce this
issue on Linux.
The solution is quite simply to set `allow_reuse_address` to `0` on our
`WSGIServer` implementation. The question is whether we want to do that
only when running a `LiveServerTestCase`, or on the base `WSGIServer`
class to prevent address stealing for `manage.py runserver` as well.
