Earlier quoted context omitted.

When you use ctrl+c, you are not killing the program, you are sending it a SIGTERM signal which essentially means « could you please stop yourself ? » so the program have a chance to clean things before exiting. kill -9 is sending a SIGKILL signal which, well, kills the program immediately.

SIGINT, not SIGTERM.
