currently space is still acting as a sort of memory manager.
For proper linking, all objects must be reachable from space, hence the plural versions like messages and addresses (even they are instances, it is the list that is important)
To dish out instance to use, the head must be kept, ie next_XXX for intergers, return addresses and messages
most of the attributes are not used at compile time ,
so they did not get updated. But the compiler uses the attribute
names (which are correct as they are set in boot), so it’s nice
to actually see them in ruby too.
