+ * usertrace is there only to be able to update the current CPU of the
+ * usertraces when there is a schedchange. it is a way to link the ProcessState
+ * to the associated usertrace. Link only created upon thread creation.
+ *
+ * The cpu id is necessary : it gives us back the current ProcessState when we
+ * are considering data from the usertrace.
