All that I said in that email is still correct.

Note that the use of volatile in that example was to ensure that the compiler 
was working at the point where I asked it to, not caching the result from some 
previous code before the snippets. The rest of the email has nothing to do 
with volatile.

And, in fact, the "volatile int" should more correctly be QAtomicInt from Qt 
5.
