wsgi: HEAD raises "Tried to write more data than Content-Length"

refers to:Running WSGI apps on Tornado servers, I deployed Django project to tornado server.
But It will raise HTTP 500 sometimes(can not control, and the 500 error is accidental)， and while use
curl --head 127.0.0.1:8888
it will raise Exception:

ERROR:tornado.application:Uncaught exception HEAD / (127.0.0.1)

Django version: 1.11.7
Tornado version: 4.5.2
Python: 3.6.0

p.s. while degrade the Django version to 1.9.*, everything is ok.

Start with the traceback locations in tornado/wsgi.py and tornado/http1connection.py, then reproduce the report with curl --head 127.0.0.1:8888 against the Django application. Compare behavior with Django 1.11.7 and 1.9.*, and consider the issue resolved when HEAD no longer produces HTTPOutputError or an HTTP 500 response.
