    Original? This was done on VAXen and in Mach ages ago.

    On Linux, there've already been two implementations, one by Hugh
    Dickens and an expanded version by Bill Irwin (presented at OLS in
    2003).

    Bill's patch was notable for going to heroic efforts to maintain
    binary compatibility, basically separating the userspace notion of the
    ABI's page size from the kernel's. How's your version fair here?
