Problem:
- there are some interdependencies here:
- creating instances requires a retain stack
- we need a Coroutine to use for our retainStack
- defining any primitive methods requires Strings and CFunctions
Solution:
- create a temporary fake stack
- create Object, CFunction and String protos sans methods.
- then add methods to Object, CFunction and String
