It might make sense to modify the autolevel code to only decrease the
level when it's really short on time, so that in the event of something
weird happening we don't lose on time.  There was a game played on KGS
without autolevel where gnugo lost on time because the opponent insisted
on playing out a broken ladder.  Shortly before it hit the ladder break,
gnugo lost on time because it was taking over a minute per move.  I think
in cases like this, it would be a Good Thing to drop the level, but I
agree that the current autolevel code would be too likely to drop it
