For debugging purpose, and if you need it in C, you can use the member
a->ob_refcount where a is any valid pointer to a PyObject. This is
more or less the equivalent of sys.getrefcount, but at the C level
(without the +1). The struct member ob_refcount is private and should
not be depended on in "real" code, but I personally like using it when
I am not sure about ref counting.

cheers,
