I've watched the memory use climb while the CPU cycles drop to 1 or 2 
percent. Presumably it does into a swap frenzy. The same thing happens 
whether r.contour finishes successfully or not.

How would I measure the size of the areas? I'll look for the area sizes 
later today. Gotta go to work now...
