--- Comment #12 from Florian Weimer <fweimer at redhat dot com> ---
POSIX 2008 removes the requirement for thread-safety in case the environment is
modified explicitly. The other unsetenv call is in the child and thus cannot
race with threads in the parent (which are not allowed to change the
environment due to the implicit read operation in wordexp).
