Thanks, I'll look at its code, but it is not a program that is needed, it 
is the libgis.a functions for a program that stays running longer than 
regular GRASS programs, and gets fooled by legagy GRASS buffers and 
squirrels-away (mapset was one) because it doesn't see changes made by 
other GRASS programs.
