-1 to that; if there are issues we should be able to find and fix them soon
enough. Even if you aren't doing long-lived YARN services yet, even llama
benefits from this zero-container-loss on AM restart.

We do have Hoya using this (introspection code because the protobuf
structures are hidden away), means that you can kill the AM and HBase &
Accumulo clusters stay up in their YARN containers, the restarted AM gets
that list of containers (and any pending events), rebuilds its data
structures and carries on as before. Sweet!
