--- Comment #7 from Kostya Serebryany <konstantin.s.serebryany at gmail dot com> ---
a related question: is wordexp() really supposed to call setenv()?
It's not just an undocumented side effect, but it also introduces
thread-unsafety
(AFAICT, setenv is not expected to be thread-safe, but wordexp is)
