The problem is that the input file triples, while the output file doubles.
As far as I can tell, I'm slurping the entire file (previous to any additions), and then foreaching over a simple array and printing the file once. I should get a doubled copy in the input file, and a single copy in the output file.
I've checked (with a print statement) and @lines contains only a single copy of the input file.
