Thanks for the quick turnaround! The interface looks good.
A few questions on the behavior:
- If a custom executor is specified, how does this impact task allocation. For example if an implementation declares it can handle 10 concurrent tasks, are we using task completion to throttle, or the number of tasks scheduled / running?
- Are there any restrictions / guidelines on the custom executor's behavior? Is it best to have a fixed pool size to match the concurrency level?

The Executor is expected to execute the task and return. The calling thread waits for it to complete using a FutureTask.
If using a pool, the pool should probably have as many threads as configured Workflow Executors. Otherwise, the Executors will block until a thread is available.
