    I'm not good with names :-)

    Note that there also might be cases where using such a memcpy
    variant might be the wrong thing to do. For example, for a very
    tightly coupled CMT cpu implementation which has the memory controller,
    L2 cache, PCI controller, etc. all on the same die and the PCI controller
    makes use of the L2 cache just like the cpu threads do, using this
    kind of memcpy would always be the wrong thing to do.
