similar to: is mutex lock on mongrel needed for activerecord?

Hi All, I''m going to end up hosting a site on a server in a fastcgi environment, but I''ve been doing most of my development under mongrel. I have a bit of code that spawns a thread, and in the thread it makes some remote calls (openuri) and does some database inserts via activerecord.

Howdy Folks, This release is after painstaking analysis of a memory leak that was reported by Bradley Taylor, reduced by myself, and then fixed after much work. You should all thank Bradley for finding the bizarre fix.
