Hi @kayousterhout, I have left a few comments (mostly nitpicks). Is the
`DataReadMethod` mainly for bookkeeping purposes? I notice that it's only being
consumed by the `JobLogger`. I wonder if we also want to show this on the UI;
it might be useful to know whether a task is reading a block from its own
memory or remotely from another machine, to explain why some tasks are slower
than others, for example.
