At least I'm not aware of any such function that could be suggested. As
far as I know, memcpy() Ix86 implementation is far from what it could
be(at least on Pentium/PPro CPUs). The only solution that I can see is
to wait for better 'official' implementation or write the routine in
assembly yourself(which of course means that you _really_ have to know
what you are doing if you want to make it fast).
