Why not use ZooKeeper?

Each RS should hold a lock in ZK while it's alive.  When the RS gets
suspended for an extended period of time thanks to the magic of the GC
(or for some other reason FWIW), it would lose its lock, at which
point the master would notice and clean up the mess.  If the RS
resumes, it would notice that it lost its own lock and do the right
thing (commit suicide or whatever you want).
