To me it means that if two threads simultanously call localeconv and any

You mean, "localeconv will *not* have a data race" ?
Yes, sorry; that's what I get for sending email in a hurry just before a
meeting on a different topic....
However, if two threads simultanously call localeconv
you might have a data race and the result might not be valid.
Yup, that's what I understood. Fortunately the unit test proves that
this is a non-issue on the systems in use nowadays. Probably because
a data race in localeconv() would lead to an MT-safety bug in *printf,
and such a bug would have been detected and fixed over the last 20 years.
Yes, and like you I don't know why POSIX is worded the way it is. If I
had more time I'd ask them....
