BRK likes to buy well run companies. Obviously a company that's broke and shutting down because of a labor dispute isn't a well run company. It would be a much better project for company that likes "fixer uppers."
GEICO was in a world of hurt when Warren began buying it...:)
Hostess was ran into the ground by incompetent management, and that would likely preclude Berkshire from buying it... however, when it was announced that Hostess was heading back into bankruptcy, the thought crossed my mind to that it would be a great thing to have join Berkshire... but only because it would be protected.... not that it would fit Berkshire as well as some other acquisitions might.
I think Nestle (which I don't even know if they are in the running) should consider it... or Mars. It looks, however, like it might be split into the bread division going to one buyer, and the snack cakes going to another (probably the maker of #$%$).
