[Radiance-general] rpiece error

[Jack de Valpine]

Actually now that I think about this, the forking has to do with 
something else, -X and -Y only specify how an image gets divided up not 
processes.... (it has been awhile since I have actually looked at how 
this works).

Perhaps another test would be to run (1) rpiece instance with the 
arguments explicitly at the command line (eg not in @args)....
