I went in and looked at this one to see how we deal with the open file
descriptior. I was worried something else could try and access or close
it later, but it looks like we just let it dangle and rely on exit()
cleaning up. So I'll apply this one as is and hopefully someone will
feel excited enough about it to clean it up down the line ;)
Cheers,
Jes
