Comment (by rhaas):

 epsilon shows up as 1/pow(epsilon,4) in the metric so 1e-4 corresponds to
 grid values of order 1e16 which is too large to feel comfortable for me.
 With 0.5 I still have values of order 16 on the grid (going down to 1.5 or
 so at the edge of the grid so a dynamic range of about 2 orders of
 magnitude). This was the reason for the large value of epsilon. It's also
 a hedge against Intel non-precise floating point arithmetic which required
 rather large values of epsilon in previous tests. I might get away with
 1e-1 (which is half a step size and would thus correspond more or less to
 a staggering the grid ) but based on the experience I had getting the
 Exact and RotatingSymmetry tests to robustly pass on both intel and gcc
 1e-4 will not work.
