There is some confusion here.  The regular PyPy (no sandbox) comes with:

* all standard libraries, rewritten not a C code, but as internal RPython code;

* for third-party modules, a way to load the standard CPython C
extension modules (slowly).

The PyPy with sandbox comes with almost no such module.  If your
application requires a specific standard library module and you can
verify that it is safe to include it, you might consider adding it,
with the proper tweaks.  For example, the "thread" module might in
theory be added, saying "threadsafe=True" on all external C functions
that it calls; but this needs efforts to make sure that it is safe.

On the other hand, third-party CPython C extension modules are a no-no
for the sandboxed PyPy.  Maybe this could change, but it's even more
work.


A bientôt,

Armin.
