谁在帮我把第四种方案实现一下啊，我的一直抱SetInformationJobObject2 Fail!，err code 为24，代码相当不完整，帮我搞搞，最好能实现对UserTime的Limit

// The C runtime library doesn't want to have any reliance on Windows' data

// values when using _beginthreadex. Since this is terribly inconvenient,
// I created this macro to perform the casting.

真正的程序员才考虑这些，我这样的三流从来没想过!
