The first option is what we do, too.

How do you evaluate a game which is stopped by reaching the length-
limit?
In UCT-Suzie I stop also when one side has a big material advantage
(captured much more stones). The length limit is related with
this, because
when a big group is captured the empty points are afterwards
filled up
again.
It's a rare occurrence that I have to stop a game early - but when
I do
I simply score the board assuming all stones are alive.
Another thing you could do (if you're the anal type) is to finish the
game after a certain point with the superko rule turned back on. You
would start having to track the keys again. But this almost seems
silly because a random game is only a guess anyway.
