-Subject: [PATCH] Fix test_workers timeout response check with Python 3.5+
-
-This check broke with Python 3.5, because REQUEST_TIMEOUT changed
-from being simply an integer constant to being an instance of the
-new HTTPStatus enum:
-https://docs.python.org/3/library/http.html#http.HTTPStatus
-on Python 3.5+, `str(http.client.REQUEST_TIMEOUT)` gives
-`"HTTPStatus.REQUEST_TIMEOUT"`, not `"408"`.
-
-Simply comparing as `int` not `unicode_type` should work with all
-Pythons (2, 3 before 3.5, and 3.5+). `int(REQUEST_TIMEOUT)` gives
-you `408` in all cases.
-
-This may not have been noticed till now because this check seems
-to be a kind of safety valve: it seems that usually, the
-`res = conn.getresponse()` call should raise `socket.timeout`
-itself, and this is some sort of backstop in case it doesn't. I
-caught this in Fedora Rawhide package builds: it seems that on
-most arches, we don't hit the bug because `conn.getresponse()`
-raises `socket.timeout` directly, but on 32-bit ARM for some
-reason we almost always hit this backstop, and that was causing
-the test to fail because of this problem.
