+/**
+ * Some general notes about ARM environments:
+ * ARM processors uses a weak memory model as opposed to the strong memory model used by Intel processors
+ * This means more permissible memory ordering allowed between stores and loads.
+ *
+ * Thus ARM port will need more hardware fences/barriers to assure developer intent.
+ * Memory barriers will prevent reordering stores and loads accross them depending on their type (read write, write only, read only ...)
+ *  
+ * For more information about ARM64 memory ordering, see https://developer.arm.com/documentation/102336/0100/Memory-ordering
+ * For more information about Memory barriers, see https://developer.arm.com/documentation/102336/0100/Memory-barriers
