*
* The cache memory begins with a table at
* DL_CACHE_START: each table entry contains
* an address and size for a cached DL slot.
*
* Immediately following the table is the
* DL_FREE_ADDR, which points to free cache
* space; following this is occupied DL space,
* and after that free space that is yet to
* be used.
