> We've been using this for our jobs for a while now and figured we would
> contribute it back. This is an observer for both worker and master (in other
> words for every node) that periodically dumps the output of "jmap -histo".
> This has been very handy for us in debugging memory issues and seeing what
> allocations are happening.
