I think I'm OK with this plan. I'm just thinking, do we have an exhaustive
list of the most annoying problems caused by the current scheme and do we
think that we could bring back some value if they were at least partially
addressed ? If so, maybe we could have the following recommendations by
order of preference:
  - new priority scheme (yet to be defined)
  - "fixed" version of the previous one to be used as a second option,
    expected to work better than nothing with existing implementations;
  - no priority handling at all (i.e. round robin or random)

Just my two cents,
Willy
