您将不得不寻找一个支持线程但没有线程安全的平台new.事实上，new(和malloc)的线程安全性是它如此缓慢的原因之一.

You will have to look very hard to find a platform that supports threads but doesn't have a thread safe new. In fact, the thread safety of new (and malloc) is one of the reasons it's so slow.

另一方面，如果您想要一个线程安全的 STL，您可以考虑 Intel TBB，它具有线程感知能力容器(尽管并非对它们的所有操作都是线程安全的).

If you want a thread safe STL on the other hand, you may consider Intel TBB which has thread aware containers (although not all operations on them are thread safe).
