I'd say this is the way to leave it, since it seems to be how you meant it
in the first place. It's just very annoying to take out the batteries if
ON/OFF is pressed by mistake while something is running.

| (...) If ON/OFF is desired while programs run, just drop the if. If ON/OFF isn't to work while programs run, it has to be this: if(nb_tasks<=3) { killall(PRIO_HIGHEST); return 0; // killall doesn't kill self } break; What does standard firmware do? (...)
