    Hi Pekka,

    What other interest have you pulled up on this? I mean, have others
    shown interest in pushing something like this. Today's slab system is
    starting to become like the IDE where nobody, but a select few
    sado-masochis, dare to venture in. (I've CC'd them ;) Perhaps it would
    make the addition of NUMA easier.

    Maybe, putting this into RT might be a way to get it tested, and help us
    with the memory management and a fully preemptible kernel.
