Thanks!

This is probably the same issue as #14: a minor memory leak that affects long calculations involving PBC geometries. I haven't been able to pinpoint it because it only appears sporadically (and typically only after several hours of runtime). I will keep looking for it. Please post any other examples of inputs that provoke it.
