Using this would require whatever process you start to handle SIGTERM properly. Most processes spawning children do this, but it&#x27;s no guarantee and one needs to be aware of this.<p>In my experience, processes doing IPC with parent gets notified of parental death by EOF on the socketpair&#x2F;pipe it&#x27;s using to communicate with the parent. This is easy to reason about and most people check return values from I&#x2F;O functions. Parents spawning children and only caring about SIGCHLD are more prone to not have the correct signal handlers set up by its dev(s).<p>IMO, any process spawning children w&#x2F;o proper signal handlers are not good citizens.
