> i think we discussed offline that as the caching gets more complex, we should either seriously rethink the caching scheme (since we know it sucks and in fact, is useless for memoryuses, relook at the BFS version to see if it makes it simpler, explore other walking algorithms (Collapse cycles into SCC's), etc.

SG. I'll dig up + play around with the BFS code, and see if that makes our lives easier. If that fails, we'll figure out something from there. :)

Thanks for the review.
