The Rete class is threadsafe but stateful. It is safe for multiple clients to share an instance, but in doing so, they will be sharing state. If you want multiple threads to share a single Rete object but keep their data separate, then their data has to be distinguishable. Every template used for client-specific data has to have a slot in which some kind of client-id is kept, and the rules need to be mindful of that client ID. Then the results for each client could be kept separate. In this scenario, it's best to use Rete.runUntilHalt() in a dedicated thread, so that the engine runs all the time.
