/**
* A special Runnable (for the particular case of Total Order) that is only sent to a thread when it is ready to be
* executed without blocking the thread
*
* Use case: - in Total Order, when the prepare is delivered, the runnable blocks waiting for the previous conflicting
* transactions to be finished. In a normal executor service, this will take a thread and that thread will be blocked.
* This way, the runnable waits on the queue and not in the Thread
*
* Used in {@code org.infinispan.util.concurrent.BlockingTaskAwareExecutorService}
