are as get_rpy_type_index() and get_rpy_memory_usage() would return,

points to. The full dump is a list of such objects, with a marker
[0][0][0][-1] inserted after all GC roots, before all non-roots.
If the argument is a filename and the 'zlib' module is available,
we also write a 'typeids.txt' in the same directory, if none exists.
