Memory allocation breakdown "100% Job"?

[maia]

The Memory Allocation Breakdown tool doesn't really feel smart. For many of my worker dyno jobs I'm being displayed "Job" with 90 or more percent memory allocation. Which isn't really helpful, as all I know is that my job with 2 million allocated objects does not allocate them in ActiveRecord or Redis. It would be great to at least display a breakdown for the classes holding the objects, and also the kind of objects.
