The third attempt filled five functions, then ran out of room planning all of
run in one turn. run and run_container are now given; spawn, Io::start,
Io::finish and answer are small todo!()s. Checked fillable: 11 of 11 passed.

Two sessions ended with nothing written, each out of room while planning the
whole file in one turn. The skeleton has the signatures, the constants and
the steps as comments; the task says to fill one function at a time.
