Although ZooKeeper easily causes a timeout, the problem is not
specific to the zookeeper driver. I think this should be fixed in
sheep/group.c.
The naive approach I'm trying to implement is:
1. add a function like 'sd_timeout_handler' to group.c, which will be
called when a timeout is detected in the cluster driver.
2. become a gateway node after sd_timeout_handler() is called.
3. try to rejoin several times, and exit the program if sheep cannot
join Sheepdog again.
Thanks,
