for my application would be really better, if I could just change the Tk::ExecuteCommand and not use threads

I think the change is needed somewhere in these 2 functions in Tk::ExecuteCommand (http://search.cpan.org/src/LUSOL/tkjuke-1.0.6/Tk/ExecuteCommand.pm): 
sub _read_stdout {

    # Called when input is available for the output window.  Also chec
+ks
    # to see if the user has clicked Cancel.

    my($self) = @_;

    if ($self->{-finish}) {
    $self->kill_command;
    } else {
    my $h = $self->{-handle};
    if ( sysread $h, $_, 4096 ) {
        my $t = $self->Subwidget('text');
        $t->insert('end', $_);
        $t->yview('end');
    } else {
        $self->{-finish} = 1;
    }
    }
    
} # end _read_stdout

sub execute_command {

    # Execute the command and capture stdout/stderr.

    my($self) = @_;
    
    my $h = IO::Handle->new;
    die "IO::Handle->new failed." unless defined $h;
    $self->{-handle} = $h;

    $self->{-pid} = open $h, $self->{-command} . ' 2>&1 |';
    if (not defined $self->{-pid}) {
    $self->Subwidget('text')->insert('end',
            "'" . $self->{-command} . "' : $!\n");
    $self->kill_command;
    return;
    }
    $h->autoflush(1);
    $self->fileevent($h, 'readable' => [\&_read_stdout, $self]);

    my $doit = $self->Subwidget('doit');
    $doit->configure(
        -text    => 'Cancel',
        -relief  => 'raised',
        -state   => 'normal',
        -command => [\&kill_command, $self],
    );

    my $doit_bg = ($doit->configure(-background))[3];
    $self->_flash_doit(-background => $doit_bg, qw/cyan 500/);

    $self->waitVariable(\$self->{-finish});
    
} # end execute_command

... is it actually possible to solve my problem so easily - just with changing this module (replace somehow the fileevent, which could be the problem)?
