Attached cannot_deallocate.patch explains why some static types cannot be deallocated. It lists (static) types which are not cleard properly at Python exit. Simplest example: --- $ ./python -c pass Cannot clear type 'object': it still has subclasses * EncodingMap * fieldnameiterator * formatteriterator * BaseException * _io._IOBase * _io._BytesIOBuffer * _io.IncrementalNewlineDecoder --- More complete example: --- $ ./python setup.py build running build (...)
