Analysis of Steve's failure so far (since it is simpler than the original one):
The tiled polygon is:

This is bizarre because a properly tiled polygon can only have at most one
GeoConcavePolygon; this has three.
There is one hole; it's repeated for all the components, which is what is
supposed to happen. However, the hole's existence is mandatory for the test to
fail, which is something I do not understand either.
Nevertheless, the failure here has to be considered the tiling failure, which
is where I'll focus my effort to understand.
