And when I used node mode, the memory usage was reduced to 73MB, it's
amazing (73MB vs. 491MB). Thanks a lot for everybody's help.
this font is a special case as it has many (also useless) kerns
using less mem is possible because i aggressively share tables
future versions of luatex might support shared kern tables and
additional font access methods so that we can squeeze out a little more
but these things are quite unpredictable
in node mode kerns are handles differently but it's slower; for fonts
that have no advanced features (contextual lookups etc) base mode is faster
