This is best done when Python is build in debug mode.
sys.gettotalrefcount then gives you the number of INCREF
calls for which no DECREF has been made; you said that
this shouldn't change.

If it does change, sys.get_counts() will give you the
number of objects per type.

Furthermore, sys.getobjects() will give you a list of
all objects allocated (excluding the result list).
