Then the libglocale in gettext-0.15 will have a nicer API - more object
oriented, not tied to the thread - than glibc. Your choice.

newlocale() returns an object; this is fine. However, to use this object,
instead of

      s = dgettext_l (domain, msgid, locale);

one has to write

      uselocale (locale);
      s = dgettext (domain, msgid, locale);

Is this faster? Four calls to __libc_tsd_set, just for nothing?

By the way, if uselocale() is really so cheap, why does libc have so many
*_l functions already? For example,

      x = strtol_l (nptr, endptr, base, locale);

is equivalent to

      uselocale (locale);
      x = strtol (nptr, endptr, base);
