title: When to use and when not to use Python 3.5 `await` ?
body: <p>I'm getting the flow of using <code>asyncio</code> in Python 3.5 but I haven't seen a description of what things I should be <code>await</code>ing and things I should not be or where it would be neglible. Do I just have to use my best judgement in terms of "this is an IO operation and thus should be <code>await</code>ed"? </p>
