作业对象的限制不起作用?

[lefttime]

我的初衷是想利用作业对象中基本信息限制来达到进程占用CPU时间的限制， 执行代码如下

......

TCHAR szCommandLine[] = TEXT("thread");		// thread程序是执行无限循环计算
STARTUPINFO si = { sizeof(si) };
PROCESS_INFORMATION pi;

HANDLE hJob = CreateJobObject(NULL, NULL);

JOBOBJECT_BASIC_LIMIT_INFORMATION jobli = { 0 };
jobli.PerProcessUserTimeLimit.QuadPart = 1000;	// 限制时间定为1ms
jobli.LimitFlags = JOB_OBJECT_LIMIT_PROCESS_TIME;

SetInformationJobObject(hJob, JobObjectBasicLimitInformation, &jobli, sizeof(jobli));

BOOL bSuccess = CreateProcess(	NULL,
				szCommandLine,
				NULL,
				NULL,
				FALSE,
				CREATE_SUSPENDED,
				NULL,
				NULL,
				&si,
				&pi);

if(bSuccess)
{
	AssignProcessToJobObject(hJob, pi.hProcess);
	ResumeThread(pi.hThread);

	CloseHandle(pi.hThread);

	HANDLE h[2];
	h[0] = pi.hProcess;
	h[1] = hJob;
	WaitForMultipleObjects(2, h, FALSE, INFINITE);

	CloseHandle(pi.hProcess);
	CloseHandle(hJob);
}

......

尽管正常运行，但得到的结果并不是我预期的...执行后的进程并未结束@@
为何出现这种情况， 请各位多多指教`~~`
