curl_multi_info_read patch review

Some guys at work created this patch and have been running with it for a while now. Could I get a few more eyeballs on this? http://www.brianfrance.com/software/php/curl_multi_read.patch Quote from our internal bug: "The attached patch implements curl_multi_info_read(), as well as fixing some memory leak issues and reference problems in the original source." Should I keep it internal or commit it? Thanks, Brian
