Increased Compatibility for NumPyPy

[This is a follow up on the work I did last semester. Some of the descriptive text is the same.]

PyPy is an implementation of Python, written in (a restricted subset of) Python, featuring an advanced tracing just-in-time compiler. It is currently the fastest implementation of Python available.

Handling embedded pointers in the JIT

So it turns out, what we do now is really silly. We just iterate over every ConstPtr() (these are GC pointer boxes within the JIT's optimizers that refer to concrete pointers) and run the GC until the object is non-movable. This isn't particularly bad with our current default GC, because it has two generations so a single collection promotes all the ConstPtrs to non-movable (and in practice they were very likely non-movable before we even try to force it). The more intelligent approach would be to have each piece of

Paul McMillan (Django security guru and all-around smart guy) and I just spent quite a while discussing this issue, here's what we came up with:

First, this is an issue which, if at all possible should be solved at the language level. This is because it's often hard to tell where data comes from a user, and where it's safe.

We're also in agreement that this should be solved at the language level, and shouldn't be configurable. It will be far to easy to deploy in an enviroment that's insecure if you get it wrong.
