Reading http://en.wikipedia.org/wiki/Double-checked_locking I'd think that the 
warnings are valid - no? Only MSVC apparently interpretes volatile in a way 
that would make this a safe pattern in C++.

Can you explain why you think it's safe to use anyways, i.e. why you want to 
ignore the warnings?

Thanks
