Description (last modified by )
Volume, f-vector and Ehrhart polynomial of polyhedra can be hard to compute, but take little memory when saving.
So we pickle those values, e.g.
+ @cached_method(do_pickle=True) - @cached_method def f_vector(self):

It looks good to me. Is there a reason why you did not do the same for functions of CombinatorialPolyhedron??

Yes, CombinatorialPolyhedron
doesn't exactly pickle. It just reduces, i.e. save enough data to initialize the object again. At some point one could think about a better way of pickling, of course.
