    OK, I'll write some code to prevent multiple threads from
    stepping all over each other when they pagefault at the
    same address.

    What would be the preferred method of fixing this ?

    - fixing do_swap_page and all ->nopage functions
    - hacking handle_mm_fault to make sure no overlapping
    pagefaults will be served at the same time

    regards,
