+## Idle view
+
+This view shows the idle state of the worker thread. A worker becomes idle when
+it has nothing to do. In particular, when attempting to get a task in the
+DelegationLock, after the first iteration the worker is considered idle.
+Similarly, when a worker serves tasks, all the time is not moving tasks from the
+queues is considered idle too.
