    If mm decision making belongs within the process scheduler, it follows
    that IO requests, dirty page writeback etc. do as well. Nope, I don't
    think we want to create a squid-uler, with tentacles extending all over
    the dang kernel.

    The thrashing problem could use some attention, but we'll have to agree
    to disagree about the scheduler growing mm, io (etc) smarts.
