    $\begingroup$ This site is read by students and scholars from innumerable countries and languages, so while I as an English speaker am amused by the title, I'm certain that there are many whose native tonge is Tagalog, or Urdu, or Mandarin, or ... are confused by the title. I would change it. $\endgroup$ Commented Jul 30 at 15:44

    $\begingroup$ @b3m2a1 Right, in Unix, a parent doesn't kill its children when it dies. It can trap some signals and kill its children before exiting, but it cannot trap a SIGKILL signal. It can trap SIGSEGV (segmentation fault), though. Proceeding after SIGSEGV seems risky. SIGKILL normally isn't sent; it should be SIGTERM, unless the process ignores SIGTERM. It's possible that the Wolfram Kernel traps these signals (except SIGKILL) and does its own cleanup. Then maybe $Epilog could work. -- Nope, it seems not, using kill.... $\endgroup$ Commented Jul 30 at 19:35
