Taint mode

Nicole King (cats-muvva.net) wrote a taint mode for CPython 3.0: http://www.cats-muvva.net/software/

Problems:

• amaury: The patch is indeed huge!

• fijall: it seems that every function that returns a PyObject must be modified

• fijall: need to patch (...) all places that might modify anything. (All side effects)

=> ncoghlan: PyPy is still a *much* better platform for that kind of experimentation than CPython
