Yes, I have been exploring on similar lines and it actually improves
performance by a bit, but it doesn't completely eliminate the need for
memmove yet which is why I'm still holding out on it.  I will continue
to work on trying to unify the two as much as possible.  I'll make that
explicit in my commit message too.

Thanks,
Siddhesh
