I imagine a loop on wait until it returns because there are no unwaited-for
children.  You can detect the "interrupted" exit status and behave
accordingly.

I'll probably make this posix-mode-specific behavior or add an option for
it in the next version.

No.  I'm not able to put everything from the Posix spec into a man page.
