note that "pdftex -ini", using the same texmf.cnf, still uses less than 7MB
of resident memory, compared to 128 MB used by xetex.

i'd imagine it could be because of unicode initialization for
characters (lccode, uccode, etc). did things change in this area since
2007? i.e. is xetex now using more memory to store unicode character
properties than in 2007?
