First, to reach the people with the most libcurl insights I'd recommend the
curl-library list instead.

You're comparing an 11 years old code base with the 6 years old version. I
don't think you can expect many libcurl hackers interested in such a time
travel journey to go back and investigate this very much. Sorry.

If you would have a problem with a modern version of libcurl I think you will
find that we'll be more interested and helpful in getting to the bottom of
things. Chances are you're seeing something we've fixed already.
