| <p>The strategy is also known by the nickname 'eat what you kill', which comes from |
| the hunting ethic that says a person should not kill anything he or she does not |
| plan on eating. In this case, the phrase is used to mean that a thread should |
| not produce a task that it does not intend to run. By making producers run the |
| task that they have just produced avoids execution delays and avoids parallel slow |
| down by running the task in the same core, with good chances of having a hot CPU |
| cache. It also avoids the creation of a queue of produced tasks that the system |
| does not yet have capacity to consume, which can save memory and exert back |
| pressure on producers.</p></div> |
