The Priority property indicates the dynamic priority of the thread. Each thread has a dynamic priority that the scheduler uses to determine which thread to execute. Initially, a thread's dynamic priority is the same as its base priority. The system can raise and lower the dynamic priority, to ensure that it is responsive (guaranteeing that no threads are starved for processor time). The system does not boost the priority of threads with a base priority level between 16 and 31. Only threads with a base priority between 0 and 15 receive dynamic priority boosts. Higher numbers indicate higher priorities.
