the magnitude should be multiplied with a constant factor F, where F is 1 when the malloc size class of list nodes is different the malloc size class of slist nodes. When they fall into the same class, the only slist benefit is having to set fewer links, so the factor F should be much smaller, closer to 0 than to 1. This could be implemented by passing the size classes in the config file. For now, we always assume F to be 1.
