+// However, multiple static variables that use the same init_seg category(i.e. compiler) are not guaranteed to destroy in any 
+// particular order. It is completely random based on how all the linking of static objects occurs. Since this command is being
+// used on our memory manager(to overwrite new/delete) - NO OTHER STATIC SHOULD EVER USE INIT_SEG(COMPILER)!!!! This static object
+// *MUST* be the final static object that is destroyed.
