另一个例子是优先级继承，它是一种锁定策略，定义了锁竞争时如何管理锁同步。
Another example is priority inheritance, a locking policy that defines how lock synchronization is managed when a lock is contested.
图1中的第二条时间线显示了发生优先级继承时第一条时间线的锁定行为的变化情况。
The second timeline in Figure 1 shows how the locking behavior of the first timeline changes when priority inheritance is in effect.
释放锁以后，系统从争用者的最高优先级队列的前端选择线程，以便试图锁定对象。
When a lock is released, the system chooses the thread from the front of the highest-priority queue of contenders to try to lock the object.
