  A region of toroidally oriented quantized flux lines must exist in the proton
superconductor in the core of the neutron star. This region will be a site of
vortex pinning and creep. Entrainment of the neutron superfluid with the
crustal lattice leads to a requirement of superfluid moment of inertia
associated with vortex creep in excess of the available crustal moment of
inertia. This will effect constraints on the equation of state. The toroidal
flux region provides the moment of inertia necessary to complement the crust
superfluid with postglitch relaxation behavior fitting the observations.
