    1) it took tasklist_lock. (it was solved already)
    2) hacky lowmem_deathpending_timeout
    3) No ZONE awareness. global_page_state(), lowmem_minfree[] and shrink_slab interface
    don't realize real memory footprint.
    4) No memcg, cpuset awareness.
    5) strange score calculation. the score is calculated from anon_rss+file_rss,
    but oom killer only free anon_rss.
    6) strange oom_score_adj overload
    7) much duplicate code w/ oom_killer. we can make common helper function, I think.
    8) John's fallocate(VOLATILE) is more cleaner.
