   General question about priority, I did not find much here [1].
   How is the value of priority interpreted ?
   Is it simply to "tag" requests ?
   Or are higher priority requests 'prioritized' over lower priority requests from an application (to a queue) ?
   
   How does it compare with [2] ? Will that be cleaner ?
