-  It uses either TBB or STD depending on what's available: as TBB can
-  quite often override `std::thread`, it is possible that TBB will be
-  used instead of STD even if the real CXX11 `std::thread` is
-  available.
-
-  As the conflicting API between TBB and STD can be quite complicated,
-  we offer a more generic `sleep_for()` function that takes
-  double-typed seconds as argument and deals with it.
