who the fuck sent 10.8 BTC to the "correct horse battery ...

Double-spending unconfirmed transactions is a lot easier than most people realise

Example: tx1 double-spent by tx2
How did I do that? Simple: I took advantage of the fact that not all miners have the exact same mempool policies. In the case of the above two transactions due to the fee drop introduced by 0.9 only a minority of miners actually will accept tx1, which pays 0.1mBTC/KB, even though the network and most wallet software will accept it. (e.g. Android wallet) Equally I could have taken advantage of the fact that some of the hashing power blocks payments to Satoshidice, the "correct horse battery staple" address, OP_RETURN, bare multisig addresses etc.
Fact is, unconfirmed transactions aren't safe. BitUndo has gotten a lot of press lately, but they're just the latest in a long line of ways to double-spend unconfirmed transactions; Bitcoin would be much better off if we stopped trying to make them safe, and focused on implementing technologies with real security like escrow, micropayment channels, off-chain transactions, replace-by-fee scorched earth, etc.

EDIT: Managed to double-spend with a tx fee valid under the pre v0.9 rules: tx1 double-spent by tx2. The double-spent tx has a few addresseses that are commonly blocked by miners, so it may have been rejected by the miner initially, or they may be using even higher fee rules. Or of course, they've adopted replace-by-fee.
