Use an entirely different method for area computation. It first transforms to a 2D plane by interpolating the great circle arcs through a Lambert azimuthal equal area projection. Then a standard 2D polygon area method is used.
Make sure the polygons always go clockwise to aid in area computation.
Fix union calculation -- it should be removing interior edges, not interior nodes.
Fix some numerical out-of-range problems in great_circle_arc.py
Remove the serial method for multi_union -- it no longer generates polygons that are compatible with calculating the area.
Make debugging images more explanatory by putting a meaningful title at the top.
