thread safe的用法和樣例：
例句
- Don't take all the warnings not to block in this function to mean that you can neglect its thread safety.
不要將所有告訴您不要在該函數中阻塞的警告理解為可以忽視它的線程安全性。 - Inserting an object in containers that will be modified by different threads has no thread safety guarantee, although in most platforms it will be thread-safe without locking.
向一個會被其它線程修改的容器插入對象是沒有線程安全性保證的，雖然在多數平台上，它是無鎖定線程安全的。
