  This paper presents an exact solution to the long wavelength perturbations
for the scalar modes and for a scalar field theory with arbitrary potential.
Locally these modes are coordinate transformations of the homogeneous
background solutions (although non-locally they are not). These solutions are
then used to discuss a couple of recent papers in which such perturbations play
a role.
  Abramo, Brandenberger, and Mukhanov have recently argued that long wavelength
perturbations have the effect of driving the cosmological constant to zero if
the higher order perturbation equation are examined. I argue that this effect
is invisible to any local observer, and thus does not constitute a relaxation
of the cosmological constant in the normal sense of the term.
  Grishchuk has argued that the standard lore on the strength of the
perturbations at the end of inflation is wrong. I discuss the disagreement in
light of the exact long wavelength solutions, and emphasize the importance of
the initial conditions in resolving the disagreement.
