Faster segment recovery after reboot - 0.8.1

Hi,

Just got a lovely email a bunch of our EC2 instances will be rebooted in a
few days. Some of them run our Kafka 0.8.1 brokers with a few hundred GBs
of data in them. Last time Kafka brokers didn't shut down cleanly it took
them maaaany hours to recover.

I just found https://issues.apache.org/jira/browse/KAFKA-1414 but I think
that's not in 0.8.1.

So.... I'm wondering if there are any config settings we could change to
speed up segment recovery?

Thanks,
Otis
