  We analyze the behavior of interacting fermions near a ferromagnetic
  Stoner instability.
  We show that the Landau damping of the spin susceptibility is a relevant
perturbation near a ferromagnetic quantum-critical point (FQCP). We argue that,
as the system approaches a FQCP, the fermionic self-energy crosses over from
predominantly momentum dependent away from the transition to predominantly
frequency dependent in the immediate vicinity of the transition. We argue that
due to this self-generated locality, the quasiparticle effective mass does not
diverge before a FQCP is reached.
