Honestly, the thread approach is probably completely wrong for the long
poll.  Ideally we'd do this in a select loop manner that lets us have a
single execution thread manage all the open sockets, and can dispatch
into work queues.  It would let us handle high load situations a lot
better.

There is no silver bullet.  Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
