All right, here's my `let's import devnull` thought process: ![](http://myweb.bloomu.edu/jba91237/Images/popcorn.gif)
1. `from os import devnull`  => didn't like this, I wanted to be clear about this var's origin
2. `import os` to have os.devnull => didn't like this either because I wrongly presumed that this would waste resources (but I just learned that import doesn't work that way)
3. hence `from os import devnull as os_devnull` => this both imports only what we need (or so I thought) and is explicit about its origin at the same time

So... yeah, I'll go ahead and make a PR with `import os`
