    a SIGKILL? i agree with the 2.2 solution - first a soft signal, and if
    it's being ignored then a SIGKILL.

    good question :-)

    i think the GFP_USER case should do the oom logic within __alloc_pages(),
    by SIGTERM/SIGKILL-ing off abusive processes. Ie. it's *still* an infinite
    loop (barring the case where *this* process is abusive, but thats a
    detail).
