  def caveats
    <<~EOS
      macOS has only 16K ports available that won't be released until socket
      TIME_WAIT is passed. The default timeout for TIME_WAIT is 15 seconds.
      Consider reducing in case of available port bottleneck.

      You can check whether this is a problem with netstat:

          # sysctl net.inet.tcp.msl
          net.inet.tcp.msl: 15000

          # sudo sysctl -w net.inet.tcp.msl=1000
          net.inet.tcp.msl: 15000 -> 1000

      Run siege.config to create the ~/.siegerc config file.
