In that case, you might be better off building such disincentives in pure
Python; for example, you control the "import" statement by changing
__builtin__.__import__(), you try to hide __builtin__.open() and
__builtin__.file(), and so on.  I'm sure there are plenty of examples of such
code out there, and you can test it on both CPython and PyPy.  And a
pypy-sandbox, which attempts to be fully safe, will never be as fast as a
regular pypy, for the reasons I mentioned.
