Changes for version 0.02
- Now uses pre-frozen signature value unless told otherwise. This saves Storable::freeze to have to be available in all threads. Can be circumvented by specifying NOT_ICED environment variable. Added OPTIMIZATIONS and CAVEATS sections to the pod.
- Added support for AutoLoader. Together with all of the other Thread:: modules, this should start saving a lot of memory.
- Removed reference tricks: we should find other ways of saving memory with threads.
