- * Theory:

- *  management system will then ignore the "offset", "next_hash" and
- *  "pprev_hash" entries in the mem_map for this page.
- *
- *  We then use a bitstring in the "offset" field to mark which segments
- *  of the page are in use, and manipulate this as required during the
- *  allocation and freeing of these small pages.

- *  We also maintain a queue of pages being used for this purpose using
