also, mem consumption reported is a bit of a lie because lua seems to

otf fonts are already quite packed in mkiv (i'm considering adding an option

is mem consumption less a second run?
Yes, dramatically less. with 4 chinese fonts loaded (I use zhfonts.tex
for testing), MKIV consumes 300-400MB.
on my machine running mk with a fresh cache gives the same lua mem usage
as with filled cache, however a fresh run tops at 1 meg while a filled
run tops ar 500 (windows vista); that document uses several cjk fonts
(relatively large due to many glyphs) and script fonts (some arabic and
zapfino as well as cambria math which are much larger fonts due to many
features

mkiv lua stats : current memory usage - 361 MB (ctx: 370 MB)
(keep in mind that at some point luatex has to load the glyph shapes and
pass them to the pdf file so there will always be otf/pfb loading at the
end of a run)
as taco mentioned, real memory usage for a fresh run is probably
somewhat lower due to fragmentation
