| See https://github.com/python/asyncio/issues/265 and https://github.com/python/asyncio/issues/268. This looks like an important regression and we should fix it before 3.5.1 goes out. The symptom is "AssertionError: queue non-empty, why are getters waiting?" from Queue.get or Queue.get_nowait. The first issue discusses the cause and a possible hack to fix it. | ||
