When GNOME shell runs on a less memory system (for example 3 GB RAM), it is usually killed by the kernel OOM-killer easily. Because, it has a higher OOM score. However, GNOME desktop environment cannot do anything when the GNOME shell is killed. This commit adjusts and lowers down gnome-shell process' OOM score to avoid being killed by the kernel OOM-killer too early. In other words, sacrifices other processes first.
