 *
 * A temporary tasks is of a more short-lived nature. It behaves like a fire-and-forget piece of code.
 * A temporary task can be created at any time by any piece of code. This creation must be dynamicaly
 * through the new() operator. When created it registers itself with the task manager, and here after any
 * references to the task must be nulled.
 * When the temporary task has done its work it must set the protected variale to true, and the
 * task instance will here after be deleted by the task-manager.
 * Temporary tasks does not need a unique name, and once created you cannot get a pointer to it again.
