title: Is there a way to prevent a process being created in UNIX-like system?
body: <p>Say there is an application with two process A and B. If I kill A, then B will create A. If I kill B, then A will create B. So if I want to kill this application completely, how to do this? For instance, in Android, some applications use this multi-processes method to keep it always running in background, which is annoying.</p>
