Its more then a few dozen but this does not justify the > 6 gig memory usage, I'd guess:

node_mem_usage=15654424 hlist, 23395466 vlist, 3925881 rule, 88525 disc, 70867847 glue, 15985958 penalty, 20651657 glyph, 2873213 attribute, 56441926 glue_spec, 2873213 attribute_list, 1 dir, 45 pdf_literal, 20458 pdf_refximage

luastate_bytes=80694 (in kb)


(the pdf is just 15 meg)
