I think you should just add that to the series, since it's kind of the
point of it all.

But ack on this, it now looks saner than what we used to have regardless.

I do wonder if we should possibly just limit the number of vma's we
dump based on core size ulimit too, but that, I think, might be a
"further improvement" rather than base cleanup.
