Alas, for pickle it's worse than that -- cPickle has lots of undocumented
features that pickle.py knows nothing about, and those features are used in
Zope.  I believe cStringIO also has undocumented features in real use ...
yup, cStringIO objects at least have an object.reset() method not in the
Python version, equivalent to object.seek(0) (but, I guess, saves the
expense of doing a LOAD_CONST on 0 <heh>).  cStringIO also provides a
C-level API.

Or you can just stop accepting C code written by Zope Corp <wink>.
