"volatile" doesn't work in other C++ compilers for multithreaded code. 
It's a huge screwup. Not only do the optimizers move things about, but 
the CPU inself reorders things in ways that move things past mutexes, 
even if the compiler gets it right. Again, see Scott Meyer's doubled 
checked locking example.

There'll be a way to do lock-free programming. Volatile isn't the right way.
