I am betting your problem is that you are adding indices out of order
(that is, not from 1 to N). If you add a key+value at a random integer
that is not 1, you will end up placing it in the hash table. This will
eventually add up to most of the keys being in the hash part of the
table due to the nature of how the hash part is resized.
