An experimental Object-based Parallel Evaluation Environment
The purpose of this gem is to explore setting up an environment that will run completely in parallel with minimum use of mutex synchronization. Actors only push the flow forward, never returning values when using the ask() method. Other methods return immediately but they should never modify the data portions of the Actors. They can be used to modify the control of the Actor.
Once a reasonable API has been established a high performance C extension will be written to improve performance.
Give it a try. Any comments, thoughts, or suggestions are welcome.

Not Your Usual Threading discussion about how OPEE use changes the way multi-threaded systems are designed.
Open Remote Encrypted File Synchronization is a sample application that makes use of the Opee gem.
- Fixed a bug in queue size reporting for the Queue class.
