steam-launch-wrapper starts every game with --oom-score-adjust 900; on
Android 900 is CACHED_APP_MIN_ADJ, so lmkd kills the running game first
when memory runs short (and on Linux 6.1 the raise becomes the process's
permanent minimum). A process in the app cannot go below the score it
inherits, so the writes that succeed from inside are raises: every
write-open of /proc/<pid|self|thread-self>[/task/<tid>]/oom_score_adj (or
oom_adj), through open/openat or fopen, goes to /dev/null, logged once.
