I find the word "simultaneous" ambiguous when it comes to events
whose duration is non-zero.

Is the problem as simple as this ?
1) A thread is interrupted while it's running strto*().
2) The other thread calls setlocale().
3) strto*() resumes with locale data which is now inconsistent
   or invalid.

If that is the case, how about :

  These functions can be safely used in multithreaded
  applications, as long as the locale is not changed during
  their execution.

or

  These functions can be safely used in multithreaded
  applications, as long as setlocale() is not called during
  their execution.

(depending on whether calling setlocale() would invalidate the
data returned by a previous call to setlocale() with the same
argument).
