The understood and expected to be safe command to use is memmove when
overlapping memory regions may be an issue.  For programmers who don't
want to concern themselves with the additional work necessary to make
use of more optimized codepaths cleanly..should be using memmove and
taking the performance hit instead of relying on memcpy..
