The problem faced by all garbage collection algorithms is the same -- identify blocks of memory that have been dispensed by the allocator, but are unreachable by the user program.
所有垃圾收集算法所面临的问题是相同的 ――找出由分配器分配的，但是用户程序不可到达的内存块。

Memory blocks can be reached in one of two ways -- if the user program holds a reference to that block in a root, or if there is a reference to that block held in another reachable block.
可以以两种方式之一访问内存块 ――或者用户程序在根 (root)中有对这一内存块的引用，或者在另一个可到达的块中有对这个块的引用。
The various garbage collection implementations use different strategies for identification and reclamation of unreachable objects, and they interact differently with the user program and scheduler.
