-slot per bucket, but that spreads the collisions to the following
-buckets. As a consequence the hash is just a start position for a linear
-search, and if the element is not in the table the index is linearly
-crossed until an empty bucket is found. When the table is full at 90%
-its size is doubled, when it's empty at 25% its size is halfed. So

-list, to be compared to at most 64 bytes of real data (depending on data
-alignment), and around 80 bytes per chunk hash (vs 32), with a minimum

-to make sure we distinguish between different files, as a single path
