Gracefully handling connection timeouts and retries will be in pre3
release. We are hoping to make pre3 as the last preview release before
1.3 stable. 

1.4 will have Self-heal functionality with journaled, lazy recovery
mechanisms that will make AFR very smooth. As of now if a brick goes
down and you will have to use tools like rsync or unison to sync
before you bring it back online.
