I can't get excited about pursuing the last ~30 seconds of delay
for launching tasks that are going to run 10 or 20 or more minutes
(where the future trend of those numbers is surely up not down).

The thing that was really significantly relevant here IMO was to
reduce the load on the central server, and I think we've done that.
Would adding longpoll reduce that further? In principle maybe,
but I'm not sure we have enough animals to make it worthwhile.
