Hm, yes. I had the impression that it's more complicated (like debconf
sometimes releasing stdin...). But in fact it seems the inconsistent
behavior only resulted from different versions of dialog doing different
things with stdin.
Hm, so why isn't that just stated clearly in the debconf documentation?
There it really sounds as if different things can happen under certain
circumstances.
