To guarantee the [safety] of a security product, the code should be [carefully] audited and the code to review must be as small as possible. Using pysandbox, the "code" is the whole Python core which is a really huge code base. For example, the Python and Objects directories of Python 3.4 contain more than 126,000 lines of C code.

Correct.  In fact I am talking about this other:

pypy.org  and its sandboxing, that is:
http://doc.pypy.org/en/latest/sandbox.html?highlight=Sandboxing

that reports the interesting issues you can have with other solutions, as CPython, for example. 
Do you have read it ?  If not, good reading  :)
