Ah, OK.  So a reference is actually an object in the sense of an
identifiable region of memory, but it's not a Python object.  When I
see "reference" I think of C++ references or git refs, which are just
names, and an object can have many references.  But the scheme you
describe is like a C stdio file descriptor, and presumably is an
indirection which allows relocating Python objects in memory.  You can
even relocate the table in such a scheme.
