> The AM should be able to exec >1 process in a container, rather than have the 
> NM automatically release the container when the single process exits.
> This would let an AM restart a process on the same container repeatedly, 
> which for HBase would offer locality on a restarted region server.
> We may also want the ability to exec multiple processes in parallel, so that 
> something could be run in the container while a long-lived process was 
> already running. This can be useful in monitoring and reconfiguring the 
> long-lived process, as well as shutting it down.
