This results in your trie having two new run-time costs:

1) More expensive trie insert/delete compared to hash

2) An extra list insert/delete to give list of all sockets

So connection setup/teardown will be more expensive and
therefore our connection rates will be lower.

Evgeniy, your ideas are beautiful in theory, but all the details
kill all of your non-trivial work and make it useless in the end.
