<p>The simplest routine is <tt>strlen</tt> which appears to be a
general win in microbenchmarks. <tt>memcpy</tt> and

behave quite differently on different CPUs.</p>

I do, this will be suitable for more testing. I'd like to see
some real-world benchmarks that show measurable improvement
before pushing any of this up into the tree.</p>
