Well, you can start children you don't need to wait on, if you really do not need to know when they die. Just start a new process group (setsid()) before calling.

if (!fork()) {
  // as child
  close(fileno(STDIN));
  close(fileno(STDOUT));
  close(fileno(STDERR));
  setsid();
  execve(argv[0], argv, env);
  /* not reached */
}

Iwould assume that's fine for "execute", but if you want to run it in debugged, you may need/want the SIGCHLD to know when it dies? Or if you are using stdin/out, deal/ignore SIGPIPE.

I can certainly fix it, so it leaves no zombies, if that is all that is needed.
