Each object allocated on the GC heap has an 8-byte overhead (sync block + method table pointer).

每个在GC堆中分配的对象有一个8字节的头(同步块+方法表指针)。

Every object has some additional bytes that the common language runtime USES to manage the object, such as the object's virtual table pointer and a reference to a sync block.

每个对象都有一些附加字节，通用语言运行库用来管理对象，如对象的虚表指针和同步锁定引用。

如果散列值不相同，将过期的数据块标记为不同步，随后的同步确保数据块是正确同步的。
