! void *memcpy(void *s1, const void *s2, size_t n)
!       Copy a chunk of memory.
!       This routine need not handle overlap, so it does not handle overlap.
!       One could simply call __memmove, the cost of the overlap check is
!       negligible, but you are dealing with a programmer who believes that
!       if anything can go wrong, it should go wrong.
