There are three functions (or at least three documented functions) in C API that "steals" references: PyList_SetItem(), PyTuple_SetItem() and PyModule_AddObject(). The first two "steals" references even on failure, and this is well known behaviour. But PyModule_AddObject() "steals" a reference only on success. There is nothing in the documentation that points on this.
This inconsistency has caused bugs (or, more fairly, potential leaks) before, see http://bugs.python.org/issue1782
Unfortunately, the suggested Python 3 change to PyModule_AddObject was not accepted.
1. Add a new function PyModule_AddObject2(), that steals a reference even on failure.
This sounds like a good idea, except the name could be prettier :), e.g. PyModule_InsertObject. PyModule_AddObject could be deprecated.
