I don't know exactly what must be done. I only know that the current
system of checking if a key was pressed (keyWasPressed()) is the only
official way to check input right now.

anything you input. This isn't unusual as apparently stdin does not
echo to stdout in Nmap like many applications (set in tty_init). We
should be able to change this without much difficulty when toggling
between modes (debugging <-> default) by modifying the terminal
attributes. Although to maintain portability, this could quickly
become a mess.

I have attached a patch that outputs script threads when they start
and when they finish. This is some example output with debugging = 1.
