Maybe we don't need a chain up to the root for this. SLOF seems to 
translate adresses by looking at the parent's ranges property. See 
translate-address in this file:

https://github.com/aik/SLOF/blob/master/slof/fs/translate.fs

This is used to implement map-in as well:

Maybe we should do the same (either in Forth or in C).
