I've stuck in a couple of lines to exclude cofactors between 61 and 64 bits. 60 might be a bit lower than optimal but it matches the bound on the rational side. The siever appears to be running normally; yield and rels/sec are down, but I can't compare that with anything until I know how many fewer relations will be needed to form a matrix.

Of course, I wouldn't like having to recompile every time I change the bounds, so if this experiment isn't a complete failure I'll get in contact with the authors.
