So the reason I was using Dir.tmpdir here is that unpack and burst leave and additional txt file and I didn't want to clutter somebody's filesystem with artifact files. Try running the command straight from the cli and you'll see the file that gets left. I'm worried that if we just use StringIO it'll just leave that file. Also, how does StringIO work for multiple files? Does it return an array of StringIO objects?
