Yah, it is :-(

I haven't seen one take that long before. I wonder how much of it was spent
doing work versus how much time was "hmm. there is a lock. let's wait to see
if it gets used. nope. clear it. oh, another lock..."

In any case, I could see an interesting doc item would be some "expected"
times for running recovery based on the DB size. I wonder if there is
correlation with static items like numbers of items, and the correlation to
runtime items like how many locks were left open, etc.
