Ok...forgot a couple of things. Bu::ItoServer now monitors all client

connections and actually cleans up behind them when they're all done.  Seems
important.  It also will cleanup any lingering sockets that are laying around
at destruction time, although right now unless you force-stop the server thread
there is no way to interrupt it.  That'll come in a bit.
