The problem is that signal_disconnect should free up some resources
we should treat the returned value as a handler_id and never look
inside in application code.

{
  my $id = $button->signal_connect('blabla' => $sub { ... });
  [...]
  $button->signal_block($id);
  [...]
  $button->signal_unblock($id);
  [...]
  $button->signal_disconnect($id);
}

No use looking inside and looks 
consistent with C version.
