Wow! It surprises me how many people are willing to accept a long chain of unconfirmed transactions. Also, there are some decent fees there for a forward looking miner to pick up. If this happens occasionally, I'd think there'd be some incentive for someone to code one.
I got bored and tried to trace them all down, but this is as far as I got before something else came up that I needed to do:
Given this transaction:
http://blockchain.info/tx/88eb395b48a6d3875d8d55a6efd34afd2e1d4e397b43f9f790479914fba0c74b(fee 0.0005BTC) (23,857 bytes)
All these later transactions are unconfirmed and waiting on it
(* indicates transactions that were traced through all subsequent transactions at the time I looked at it):
