I don't know how popular, or well known, this little tool is, but I was wondering if there was ever any consideration for it to be merged into the main CVS tree and distributed with part of PHP, instead of a 3rd party patch. Link: http://php-fpm.anight.org/
I'm pretty sure this is the right list, let me know if it's not. I did some searching and couldn't find any previous discussion, either.
