There is a certain competitive advantage to _not_ recycling the
blocks at this time. If another effort to crack is organized,
they will have to check the entire keyspace rather than simply
looking at our stats to see how far we've gone and then starting
their own search at that point. So, leaving unidentified(to the
public) holes in the keyspace is a good thing(sort of).

Yes, I know that we really are not in competition here, that the
goal is to crack, not to be the cracker, but then again...
