/**
* Processing strategy that processes the {@link Pipeline} in the caller thread and does not schedule the processing of any
* {@link Processor} in a different thread pool regardless of their {@link ProcessingType}. While processing of the flow is
* carried out in the caller thread, when a {@link Processor} implements non-blocking behaviour then processing will continue in a
* {@link Processor} thread.
* <p/>
* This implementation offers an optimization over {@link DirectProcessingStrategyFactory} by reusing a single stream instance for
* each callee thread.
