Message400384
The return code of python on linux/MacOS when the program is ended with a KeyboardInterrupt should be -2, when running with multiprocessing the exitcode is 1. I've attached a reproduced example.
From The Process.join() docs: https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Process.exitcode
> A negative value -N indicates that the child was terminated by signal N.
