Actually, i had a look at bigarrays, and it's one of the solutions I
considered. However, I'd like to keep strings as data structure, because
the operations I have to perform take a string as an argument, and not a
(char, Bigarray.int8_unsigned_elt, Bigarray.c_layout) Bigarray.Array1.t,
and it would be a pain to change all these functions (if I change them,
I'll probably bind mmap() and munmap() directly and call them with
MAP_ANONYMOUS, but I'd rather not do that).
Thanks,
Julien
