Loding marshaled data is still expensive, so we would want to load only
one time in the process's lifetime.  There would be two method to
achieve this.  The one way is explicitly loading a locale data as,

let locale = load_locale "ja_JP" in 

...

let s = string_of_int ~locale 1234567 in

...


But the syntax is a bit heavy.

Another way is cashing them in (Weak)Hashtbl.  (Camomile does this
currently)

If we have a support for persitent data across different instances of
the locale library with different uid and permissions, then it would
be a way to go.  Unfortunately, we do not have such a one, unless we
throw away portability.
