Detailed Description

Thread that is executed when there is nothing to do for this core.

Using the IdleThread simplifies the idea of waiting and is an answer to the questions that arise once the ready queue is empty.

Note
Instance of this class should never be inserted into the scheduler's ready queue, as the IdleThread should only be executed if there is no proper work to do.
