test_asyncio.test_start_tls_server_1() got many fixes recently: see bpo-32458 and bpo-33674... but it still fails on Python on x86 Windows7 3.x at revision bb9474f1fb2fc7c7ed9f826b78262d6a12b5f9e8 which contains all these fixes.

The test fails even when test_asyncio is re-run alone (not when other tests run in parallel).

The test fails also on x86 Windows7 3.7:

The Windows7 buildbot is known to be slow. For example, test_value() of test_multiprocessing_spawn failed with a timeout (15 min) on x86 Windows7 3.x:

Maybe something is wrong with my karma, I don't know. Or test_asyncio just hate me.
