`runN`

For completeness, here's [[spawn], which is totally routine:

        sub spawn {
          my $pid = fork;
          die "fork: $!" unless defined $pid;
          return $pid if $pid;
          warn "@_\n" if $opt{v};
          exec @_;
          die "exec: $!";
        }

I probably use runN every day
