Of course it would still be better if muppet could get into the
habit of using three-argument open() with lexical filehandles.
:-)

    sub run_convert {
        my @cmd = @_;
  
        my $main_loop = Glib::MainLoop->new;
  
        my $pid = open my $child, '-|', @cmd
            or die "can't fork convert: $!";
  
        Glib::IO->add_watch (fileno $child, ['hup'], sub {
            $main_loop->quit;
            FALSE;
        });
  
        $main_loop->run;
  
        close $child or warn "convert died with exit status ".($? >> 8)."\n";
    }
