> When launching a worker the supervisor will read in the complete topology to
> get a small amount of data out of it. This can be very large. In the past
> we would launch the workers one at a time, so we only needed enough memory to
> read it in once, now we are doing it in parallel, and lots of these tend to
> show up very close to one another. We need to find a way to make it so that
> we read the data one, and ideally cache it someplace that everyone can share.
