Thanks.  The latency number is interesting and it confirms what we were
seeing looking at cpu usage. 

We don't have an inexpesive way to get a packet from the outside world
to a network namespace.

Now if we can figure out why the routing code or the bridging code
seems to be performing extra packet copies, perhaps that can be fixed.
