> What happens:
> Thread 1 creates a stateful session and spawns daemon Thread 2 (with the correct TCCL).
> Thread 2 calls fireUntilHalt() on the stateful session, which suspends that Thread.
> Thread 3 calls halt() on the stateful session, which will cause Thread 2 to stop *once all the rules have finished firing*, however returns immediately.
> Thread 3 calls dispose() on the stateful session, *but the rules might not have finished firing*.  This could cause unpredictable results.
> What needs to happen:
> Thread 1 creates a stateful session and spawns daemon Thread 2 (with the correct TCCL).
> Thread 2 calls fireUntilHalt() on the stateful session, which suspends that Thread.
> Thread 3 calls halt() on the stateful session, which will cause Thread 2 to stop once all the rules have finished firing, however returns immediately.
> Thread 3 calls join() on Thread 2, which will return *once all the rules have finished firing* and Thread 2 is done.
> Thread 3 calls dispose() on the stateful session safely, as now the rules have finished firing.  This means predictable results.
