Here's a pathological scenario:
Let's call the BIP110 enforcing chain Coin A and the non-enforcing chain, which very well may be longer, Coin B
The two chains split. Coin A trades at 100:1 Coin B. Miner buys 1000 Coin A for 10 Coin B and then starts mining on the BIP110-enforcing chain afterwards. Coin B chain get wiped out when enough miners do this and the BIP110-enforcing chain gets longer than the non-enforcing chain. Not only did the miner gain 1000 BTC on the now single chain, the 10 BTC that was spent is returned because it's no longer a valid tx on the now-single chain!
Game-theory wise, this is extremely profitable, depending on the price ratio. For me, this will be a test of how optimized for game theory miners are.
