    Subject[PATCH 2/3 for 2.6.38] oom: select_bad_process: ignore TIF_MEMDIE zombies
    select_bad_process() assumes that a TIF_MEMDIE process should go away.
    But it can only go away it its parent does wait(). Change this check to
    ignore the TIF_MEMDIE zombies.

    Note: this is _not_ enough. Just a minimal fix.
