- * Shadow table DB element
+ * The implementation includes 3 tables per table table type.
+ * - hash table
+ *   - sized so that a minimum of 4 slots per shadow entry are available to
+ *   minimize the likelihood of collisions.
+ * - shadow key table
+ *   - sized to the number of entries requested and is directly indexed
+ *   - the index is zero based and is the table index - the base address
+ *   - the data associated with the entry is stored in the key table.
+ *   - The stored key is actually the data associated with the entry.
+ * - shadow result table
+ *   - the result table is stored separately since it only needs to be accessed
+ *   when the key matches.
+ *   - the result has a back pointer to the hash table via the hb handle.  The
+ *   hb handle is a 32 bit represention of the hash with a valid bit, bucket
+ *   element index, and the hash index.  It is necessary to store the hb handle
+ *   with the result since subsequent removes only provide the table index.
+ *
+ * - Max entries is limited in the current implementation since bit 15 is the
+ *   valid bit in the hash table.
+ * - A 16bit hash is calculated and masked based on the number of entries
+ * - 64b wide bucket is used and broken into 4x16bit elements.
+ *   This decision is based on quicker bucket scanning to determine if any
+ *   elements are in use.
+ * - bit 15 of each bucket element is the valid, this is done to prevent having
+ *   to read the larger key/result data for determining VALID.  It also aids
+ *   in the more efficient scanning of the bucket for slot usage.
