I am confused. Ruby '\n' is not equivalent with Ruby "\n", so a
difference would not be unexpected. (The size of the difference perhaps)
In Python, "\n" and '\n' are the same and equivalent to Ruby "\n".

It appears to me that the original comparision is null and void, since
it does not do the same thing. Has anybody looked closer at the output
of the Python vs the Ruby versions, like running a diff? It sure looks
different to me...
