Only as additional synchronized form of lazy init (in addition to 
conventional static locals) when you explicitly tell compiler 
(expressing it in source code, not via compiler option) that you 
want this or that static local instance to have synchronized init. 
C++ made a particular principle of the idea that "you should not 
pay for what you don't use."

Right.
