This was posted on concerning the
present status of the JitterVM:

"The Jitter VM was released for Squeak 1.31. Users should note that it
has a serious bug in the way it caches the structure of classes. If you
write code that redefines a class with many subclasses, you may crash
shortly afterwards. I have written test code that crashes it every time.
Ian has not released a Jitter for 2.0 or 2.1. He is working on a
from-scratch new one. Presumably it will not have the cache bug. -- Ted
