I will not svnmerge these changes into py3k as the amount of time and effort that would take equates to running the static analyzer again just before 3.2 is released and possibly catching more changes (and maybe even a newer version of Clang at that point).

Have you looked into teaching clang's static analyser about Python's refcounting rules?  Clang's analyser can tell you about problems related to reference count management for Objective-C code and doing the same for code using the CPython API would be usefull.

It's mostly just finding stuff like unneeded variable initialization or variables that are never used (compilation is picking up unused returned values, almost all from PyObject_INIT).

I have gone through the underscores and the 'a's in Modules and already have six modified files, so the final count might be a little high. Do people want individual entries per file, or simply a single entry that lists each file modified?
