- new proc_is_runnable() macro to test whether process is runnable. All tests whether p_rts_flags == 0 converted to use this macro - pick_proc() calls removed from enqueue() and dequeue() - removed the test for recursive calls from pick_proc() as it certainly cannot be called recursively now - PREEMPTED flag to mark processes that were preempted by enqueueuing a higher priority process in enqueue() - enqueue_head() to enqueue PREEMPTED processes again at the head of their current priority queue - NO_QUANTUM flag to block and dequeue processes preempted by timer tick with exceeded quantum. They need to be enqueued again in schedcheck() - next_ptr global variable removed
