rethinkdbdash: Fail to create a new connection for the connection pool.

Just trying out the library for the first time, with a simple

> r = require('rethinkdbdash')({db: 'test'})

I am getting the following:

Exiting slow growth mode

RethinkDB is running, as I am able to access it via both the dashboard and the rethinkdb package, and the port is default.

I am able to use the resultant r object to query the DB, too.

> r.tableList().run().then( console.dir )
