    Yes, try_to_free_page almost but not quite handles no wait requests
    suitably (ipc shrinking ignores no wait at least). There are one
    or two other stunts we can pull to make DMA requests for multiple
    pages more reliable.

    I've been working on page_alloc.c and kmalloc.c for a while now
    but I got side tracked with the Cyrix stuff which turned out to
    be more involved than I thought :-(.
