            Bug ID: 15607
           Summary: Add threadsafe version of getenv()
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org

gnome-settings-daemon is a daemon running in a GNOME session to apply stored
settings (such as the user's preferred locale) to the running session and its
own children (such as applications launched using the media-keys).

We started hitting SEGVs somewhat randomly recently:
https://bugzilla.gnome.org/show_bug.cgi?id=701322

which are caused by races between getenv() (as used by the glibc's gettext
implementation) and setenv() (called by gnome-settings-daemon to change its own
environment).

Having getenv_r()/setenv_r() would avoid this problem and make our
implementation more straight-forward and cleaner.
