I don't get this. When a thread becomes inactive, active threads overtake it and it naturally drops to the back of the list. It would only come back to the beginning if someone posted in it (aka "bumps" it) again.
That's not the issue. The issue is long active threads that never end. It may be a good idea to retire active threads after a while, even if they are still active.
