Comment 2 for bug 1526613

Attached are the changes to the asyncio module between 3.5.0 and 3.5.1 as packaged in ubuntu. Reverse applying this patch against 3.5.1 makes the cython test-suite pass.

Otherwise cython test suite fails on any architecture as seen in https://launchpad.net/ubuntu/+source/cython/0.23.4-0ubuntu1
E.g. amd64 https://launchpadlibrarian.net/232316886/buildlog_ubuntu-xenial-amd64.cython_0.23.4-0ubuntu1_BUILDING.txt.gz
