Source docstring:

Promise to return a connection when one is available. If no connection is
available put the promise into a FIFO queue to get the next available
connection.

(defn connection
  []
  (locking lock
    (let [p (promise)
          conn (.poll connq)]
      (if (and conn (not (.isClosed conn)))
        (deliver p conn)
        (.offer promiseq p))
      p)))
