There had been such an implementation, but I removed it from the set
because there was no consensus how it should look like. I'd prefer
that someone else does it. If you want to read things up, there has
been a discussion on this list in May last year.

Your patch looks like the minimal thing that one would expect. For me
personally that does not seem good enough. One of the things that
bother me is that `memset` could have varying processing times, not
only depending on the length of the input (which is unavoidable), but
also depending on its contents.

Anyhow, Rich had elaborated a whole strategy how this feature would
better fallback to a builtin, if such a builtin exists. So I prefer
them doing it, whenever they are ready.

Thanks
