I would do a 0.000001 auto cash out at any 42 pools now (Txfee is 0.00000001, which is only 1% of that).
So at least in the event of an successful attack, you won't be having more than that in the pool. But any time after the attack until it's get fixed your hash power is lost. That's the best you could do rather than going on a super pool with enhanced securities, which is just not available for 42 yet..
