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 /_sources/library/asyncio-eventloop.rst.txt HTTP/1.1" 500 59
