Squid-2.3.DEVEL2: async-io is a bit keen on warn on thread usage
    Async-IO is a bit keen on give a warning about thread usage. This
    patch increases the burst filter threashold a little bit. Hopefylly I will
    find time to address this at the real root of the problem (bursty store
    recycling) in the near future.
