C++中内存管理是一件比较麻烦的事情，因为需要手动进行内存的分配和释放，很容易出现内存泄漏的问题。
在C++ 11的标准制定过程中，Bjarne Stroustrup（C++之父）觉得Java的内存管理比较好，想要参考Java的方法改进C++。
当他给C++标准委员会提起这件事的时候，来自Microsoft和IBM等公司的代表马上不乐意了。代表们说，如果C++采用Java的内存模型，Java的运行速度至少会慢上一倍，你可不能这么对Java。
英文原文
Bjarne Stroustrup: We thought, at least I thought that Java had a pretty good memory model, so why don't we adopt that, and it'll save us a lot of work. So i mentioned this, and the representatives from various important groups such as Microsoft and IBM says, you can't do that, because if you adopt the Java memory model for C++, our Java implementations will slow down by at least a factor of two, and you just can't do that to Java.
