Hi Christopher,
I mant to copy the list, I am doing this again now.
Wow, I was not aware that Emacs caches by content, this is an important piece of information. I guess this removed the main concern I had. Thanks for looking it up in the code and showing it to me. I am not sure if I understand that code completely, but i trust your judgment.
