[erlang-questions] escript cutting output

[Tim Watson]

Hillarious. :)

I was wondering if waiting on receive would help, but of the course
the issue was the time being taken by the io:format call and that
didn't change until you added the extra call(s). I've certainly
learned something useful about the io subsystem on this thread and
will poke around in the code to learn more.
