python: Unbounded memory buffering in SelectorSocketTransport.writelines()

A flaw was found in Python. In certain configurations, the asyncio.SelectorSocketTransport.writelines method fails to signal the protocol to clear the write buffer when it approaches capacity. Because of this, protocols would not periodically drain the write buffer, potentially leading to a denia...
