I only got a packet loss here :)

We should be able to account for all packets sent and received - our
transport is reliable.  Unfortunately:

- the way ping is used (or some would argue, ping itself) isn't very
robust.  As a simple example, the first ping below is
non-deterministic (it can send one or two ping packets):

ping -q      -w 1 -n -c 1 "$@"
ping -q -i 2 -w 1 -n -c 1 "$@"

(see one-ping.sh)

One idea was to migrate to hping3

- I'm beginning to wonder if there's a race between whack
--trafficstatus showing a connection being up and a connection being up?

I have never seen that.
