今天run了一下cobble的例子，用windview得到的图表如附件。

看到那个crunch 的task，就是计算10个点的平均值的那个，在执行过程中，都有locked state 状态，相关的解释如下：

The VxWorks scheduler can be explicitly disabled and enabled on a per-task basis with the taskLock( ) and taskUnlock( ) routines. When preemption locking is enabled (shown by the stipple), priority-based preemption does not occur unless the task explicitly blocks or suspends. When the preemption-locked task unblocks and begins running again, preemption is again disabled. Note that multiple nested calls to taskLock( ) may be made; each one must be explicitly unlocked before normal priority-based scheduling is enabled. In addition, note that preemption-locked tasks are still subject to interrupts.

可是在源码里并没有看到这两个调用,请问为何会出现这种状态？
