 running v.surf.rst on grass 70svn on an AMD vishera 8 core 3.5 Ghz cpu
 with 8 GB RAM .  Fired it up with the defaults  for a section of Western
 North Carolina with 77 million bare earth points to create a 23 million
 cell 20 ft resolution grid.  I will attempt to attach screenshots of
 completed grid and grid complete with v.surf.bspline.  Region was set to
 output v.surf.bspline raster.
