 // AlignedMemory is a POD type that gives you a portable way to specify static
 // or local stack data of a given alignment and size. For example, if you need
 // static storage for a class, but you want manual control over when the object
 // is constructed and destructed (you don't want static initialization and
 // destruction), use AlignedMemory:
