+ "In concurrent programming, sometimes it is desirable to make sure
+commonly accessed shared data is not all placed into the same cache line.
+Updating an atomic value invalides the whole cache line it belongs to, which
+makes the next access to the same cache line slower for other CPU cores. Use
+CachePadded to ensure updating one piece of data doesn't invalidate other
+cached data.")
