This seems consistent with the errata section of the relevant standard noting that some known implementations are not entirely standards compliant in this manner https://pubs.opengroup.org/onlinepubs/9699919799/functions/kill.html despite claiming standards compliance at https://www.ibm.com/docs/en/zos/2.1.0?topic=functions-kill-send-signal-process |

On z/OS, EPERM is returned if the process being killed is a zombie. However, this shouldn't be treated as an error, so return 0 instead. Co-Authored-By: Muntasir Mallick <mmallick@ca.ibm.com> Co-Authored-By: Gaby Baghdadi <baghdadi@ca.ibm.com>

On z/OS, EPERM is returned if the process being killed is a zombie. However, this shouldn't be treated as an error in
uv_kill()since it's already terminated, so return 0 instead.
