I just removed the tmpdir thing because I didn't need it in my use case and I was just trying to get things working at 3AM. Really, it should probably use `Dir.chdir`. I'd have to think more about how to do the tmpdir thing automatically and safely.

The dev can use `Dir.chdir` on their own if they want too.
