Re: [Patch] Document clarification of performance improvements in Perl 5.13.3

I agree, it's not a great changelog entry. Sorry about that.

I don't think this is great either. Are those actually quantifiable
performance enhancements? All the commit messages say is that the cache
pressure was slightly reduced, not that anything is now measurably faster.

Maybe something along the lines of "Reduced number of cache misses in
the very commonly used functions C<warnings::import>, C<warnings::bits>,
C<vars::import>, and C<Carp::import>, as well as when accessing
filehandles for reading"?

Your patch mentioned strict.pm. I don't see any similar changes to
that. Am I missing anything?
