On table creation, each entry in the handle data table is populated with a pointer to the next entry in the table. When a new handle is created, that pointer is moved into offset 0x8 of the KProcessHandleTable info struct to use for generation of the next handle.

The final handle that gets returned when a handle is created is (handle_index | (handle_total << 15)), basically they take the index into the handle data table and OR that with the total handle count << 15. This returned value is the one that gets passed back to the running application and is used to look up the HandleData entry in the table.
