Maybe the frozen modules should be a global static? This should not change between VMs.

Maybe, but it's possible that someone would want to inject a frozen module into one VM to wrap their API or something, but want to use another vm for something different. I've done that myself in another project that uses RustPython.

In preparation for threading; we want to keep some properties of the vm consistent across threads, so I'm moving the ones that should be into an
Arc.
