关于ajax内存释放问题

[随风飘荡的火焰]

	
 1.     var request = new Object(); //new一个对象
         	request.ajax = false;
	
 2.	request.ajax = new XMLHttpRequest(); //新建request


	  //然后
 3.     request.ajax.onreadystatechange = processRequest(request);

         //最后在响应函数中
 4.     processRequest = function (request) {
            if (this.readyState != 4) {
		return;
	    }

            // 重点在这里
            delete request.ajax;
            request.ajax = null;
                   
            delete request;
            request = null;
        }

问题：
请问有内存泄漏吗？

// 重点在这里
delete request.ajax;
request.ajax = null;

delete request;
request = null;
