I think this should either return the exit code (if it's there) OR the signal n + 128. This is a standard procedure, e.g. in Bash: https://tldp.org/LDP/abs/html/exitcodes.html

Returning just the signal number (e.g. 9 for KILL) could be confused with the actual exit code 9.

You are right! I could not easily find a constant in libc or in the std library, so I hardcoded 128 with a comment.
