[AUVRAY Sebastien]

Hi Ian,
Sorry I am away until end of May.
Will look at this asap (beg. June).
By the way for my tests I got also this 1st try >1minute (but get rid
of best and worst case so that wouldn't appear in the average).
Concerning the pack if you could give me access to the clean repo you
did, thanks.
Sebastien
