"In practice, volatile doesn't do what you mean". What?? Volatile is designed to prevent compiler optimizations on a variable. It's highly, highly, highly recommended for multithreaded programming. Don't attempt multithreaded programming without volatile. Your program may work fine for years and suddenly crash out of nowhere.
