if you look at http://wikis.sun.com/display/WideFinder/Results, there is
OCaml version with 00:08:12 elapsed time
and using regexp instead Boyer-Moore. This is far far away what erlang can
do except with specialized mmap ad hoc linked in driver I guess.
If OCaml version upgraded to Boyer-Moore prefix match I guess it can be
better but not so much because this task is strong I/O bound.
