说明：  使用Windows 2000 / XP的API函数，编写一个包含两个线程的进程，一个线程用于模拟内存分配活动，一个线程用于跟踪第一个线程的内存行为，而且要求两个线程之间通过信号量实现同步。
(use Windows 2000/XP API functions, including the preparation of a two-threaded process, a thread used to simulate memory allocation, a thread used to track a thread of memory, but also between two threads through the synchronized signal volume.)
