[3.6] bpo-33469: RuntimeError after closing loop that used run_in_executor (GH-7171) by miss-islington · Pull Request #7179 · python/cpython

@1st1: I am sorry, I cancelled the AppVeyor job because I'm waiting since 2 hours for AppVeyor to run on my PR #7175 which blocks 3.7rc1 release. On this PR, the VS 2017 job of AppVeyor was "queued" since 31 min, whereas the "VS 2015" job completed. Please retrigger manually the job.
