Since the final page is a big stencil, I think you should be able to
count how much memory it consumes in cells and string literals. That
gives some ballpark estimate of how memory intensive the backend is.
Since grob typically constructs one stencil, I would be surprised that
the stencil machinery would use more memory than the whole property
list machinery (and hence: that it would make a big dent in memory
usage), but that's your gut feeling against mine, which is what I want
to get away from.
