Thanks for the report and script, Jaakko. There's a problem with
circular references here. I have a fix involving weak references, and
just need a day or two to test the cases of interior rings and sub-geoms
of the multipart types. Work around in the meantime is to break the
circular references in your code like:
...
poly = Polygon(points)
poly.exterior
...
poly._exterior = None
# end block
