When I was looking at configuring the ageing time last time, my finding 
was that the ageing time could not be set very low as there was some 
part in the DSA layer etc, and confusion wrt units. I think the minimum 
secured was like around 2 min. (not validated), which is not that much 
of an improvement for fast testing. If you know what would be a good low 
timeout to set, I would like to know.
