What system() does (at least on UNIX-like OSes) is fork a child, call exec() with a new process and wait for the new child to terminate (plus some other stuff to get rid of misbehaviours). A child process can still get a signal from every process of that user or that belongs to the user root (including the parent process, but not exclusively).
