Hi, While analyzing some code I came across the following situation: - User calls run_until_complete for some Task - The task itself calls loop.stop() at some point - run_until_complete raises TimeoutError Here is a very simple example: https://gist.github.com/saghul/4754117 Something seems a bit off here. While one could argue that stopping the loop while run_until_complete is ongoing, getting a TimeoutError doesn't feel right. I think we should detect that the loop was stopped but the future is not done and raise something like NotCompleted or FutureNotCompleted. Thoughts? -- Saúl Ibarra Corretgé http://saghul.net/blog | http://about.me/saghul
