The C++11 standard (the only one aware of multithreading) mandates that initialization of static variables at function scope is thread-safe.
Really? I didn't pay attention to ever twist or turn of the process of standardizing multithreading, but it greatly surprises me to hear that, because it would impose an overhead on those function-static variables that don't need synchronization. Can you cite the paragraphs that give this guarantee?
In this draft version http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3035.pdf the relevant paragraph seems to be 6.7.4. Mika Heiskanen
