These areas allow tasks to use memory without being required to block if the garbage collector needs to free memory in the heap.

如果垃圾收集器需要释放堆中的内存，则这些内存区域将允许任务使用内存而不需要中断任务。

A generational collector is free to use a different collection strategy for different generations and perform garbage collection on the generations separately.

分代收集器对不同的代可以自由使用不同的收集策略，对各代分别进行垃圾收集。

Thread IDs are reused often, so there could be a case where a thread died without releasing the slot, and comes up and allocates a new slot before garbage collector could free it.

通常线程ID会得到重用，因此可能会出现这样的情况，即一个线程已经死亡，却没有释放相应的槽位，并在垃圾收集器释放该槽位之前，再次使用了这个线程ID并为其分配一个新的槽位。
