We're still experimenting what's triggering this, it appears with Python 2.7.13 and Pytest 3.0.5:

However this comes from a clean Debian Testing (Stretch) on i386.

testing/test_gateway.py::TestBasicGateway::test_gateway_status_busy から始め、報告された Python 2.7.13 と Pytest 3.0.5 の環境で失敗を再現します。両方のチャネルを閉じた後の thread-socket gateway の remote_status 値を追跡します。テストが numexecuting が確実にゼロに到達することを確認し、他の gateway ケースにリグレッションが発生しなければ完了です。
