Why do you need to keep them?  The only reason a fork could return is if someone thought it was the best chain and kept working on it.  This means they would have all of this information, which should be retrievable.    You need to catch up anyway if you disconnect from the network and return in an hour, this seems like it would be the same case.  You keep track of what you think is the best chain, if someone gives you evidence of a better one, you replace what you know with what they give you.
