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
