61 /* Implements the "construct on first use" idiom to avoid any static
62 * initialization order fiasco.
64 * Note that thread-safety of the initialization is guaranteed by the
65 * C++11 language standard.
67 * The pointer itself (not the memory it points to) has no destructor,
68 * so there is no deinitialization issue. See
69 * https://isocpp.org/wiki/faq/ctors for discussion of alternatives
