def self.select_random_port(low, high, host = "localhost")
  raise "'low' must be lower than 'high'" unless low < high
  port = nil
  begin
    port = low + rand(high - low)
  end while Socket.socket_in_use?(host, port)
  port
end

.socket_in_use?(host, port) ⇒ Boolean

OPTIMIZE. Is there a better way to do this? Feels ugly to me.

Returns:

  • (Boolean)
