Title: events.state: Default to 1000 tasks in memory

The previous default was a _lot_, and responsible for up to 500 MB of
memory usage per worker MainProcess - this caused memory pressure on
our production boxes. I now know we can turn this off with
--without-gossip, but lowering this by an order of magnitude be a lot
nicer to everyone who doesn't specify this optional flag.
