Well monsoon gets it but it doesn't set any speed records in the process:

There are approx 10M check extensions fired between depth 10 and 11 as well as
about 1M one-reply extensions. I think this explains the slowness, the tree
simply explodes. I'll have to experiment with how to restrict those lines
better.
