1970This file can be used to adjust the score used to select which processes
1971should be killed in an out-of-memory situation. Giving it a high score will
1972increase the likelihood of this process being killed by the oom-killer. Valid
1973values are in the range -16 to +15, plus the special value -17, which disables
1974oom-killing altogether for this process.
