1.) We started paying attention and caring about delays
2.) Load increased, by as much as 2x depending on time of day

When I say "seemed to be working fine", that was right after putting
everything together and verifying that messages were flowing at something
that, to my eyeballs, seemed like a reasonable rate.  Right after startup,
I didn't really watch for any kind of delay because I was basically doing "
stomp_drainer.pl |pv >/dev/null".
