+/* Round robin active object scheduling for Qt apps.
+ *
+ * Qt and Symbian have different views on how events should be handled. Qt expects
+ * round-robin event processing, whereas Symbian implements a strict priority based
+ * system.
+ *
+ * This scheduler class, and its use in QEventDispatcherSymbian::processEvents,
+ * introduces round robin scheduling for high priority active objects, but leaves
+ * those with low priorities scheduled in priority order.
+ * The algorithm used is that, during each call to processEvents, any pre-existing
+ * runnable active object may run, but only once. Active objects with priority
+ * lower than EPriorityStandard can only run if no higher priority active object
+ * has run.
+ * This is done by implementing an alternative scheduling algorithm which requires
+ * access to the internal members of the active object system. The iSpare member of
+ * CActive is replaced with a flag indicating that the object is new (CBase zero
+ * initialization sets this), or not run, or ran. Only active objects with the
+ * not run flag are allowed to run.
