对于调用堆栈上的每个函数，当记录间隔时，探查器分析都会向该函数的四个数据值中的一个或多个添加此间隔。
For each function on the call stack when the interval was recorded, the profiler analysis adds the interval to one or more of four data values for the function.
对于每个间隔，探查器分析都重新构造在此间隔结束时存在的调用堆栈。
For each interval, the profiler analysis reconstructs the call stack that was present at the end of the interval.
探查器在此调用期间不应进行阻止，因为堆栈所处的状态可能不允许执行垃圾回收，因此不能启用抢先垃圾回收。
The profiler should not block during this call because the stack may not be in a state that allows garbage collection, and therefore preemptive garbage collection cannot be enabled.
