[issue27682] wsgiref: Windows Error 10053, ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine

I think this is an issue with wsgiref handling client closure rather than a 
Windows/Django bug. I saw this sporadically but not consistently while running 
`make serve` to serve the docs which uses wsgiref simple server to serve docs 
on my Mac OS. Related issue34547 with a PR that catches ConnectionAbortedError 
and returns.

PR link : https://github.com/python/cpython/pull/9713/

Sample traceback while serving docs locally with `make serve` on Mac OS: 

127.0.0.1 - - [12/Oct/2018 10:56:57] "GET

I'm still seeing this with

Python 3.6.3
Django 2.0.1
Windows 10 Pro Version 1709

Was this determined to be a Django bug?
