Just to clarify, you're recommending something like
    proc->me = PyCObject_FromVoidPtr(proc, NULL);
+        if (proc->me == NULL)
+            elog(ERROR, "could not create PyCObject for function");    PyDict_SetItemString(PLy_procedure_cache, key,
proc->me);

correct?  (Hm, and it looks like we'd better move the pfree just above that...)

Yeah, and since we'll have to back-patch it, a fairly noninvasive patch
would be nice.  Will you work on that?
