Alias mappings

I wonder if this allows to create alias mappings that are still copy-on-write and compatible with fork. This would allow transparent coloring of pointers without hardware support for address masking. This would be quite interesting to malloc implementations because it can help with determining allocation metadata efficiently during deallocation.
