It is unusual to pass in a function which has side-effects to "map",
because this function is usually used for functional programming. In
Python, it is more idiomatic to join together the lines before
printing them out, like this:
   sys.stdout.write("".join(stdout_lines))
   sys.stderr.write("".join(stderr_lines))

Cheers,

David
