I wrote a blog entry, as well as a tool, on saving memory in Ruby on Rails using fork() and copy-on-write in modern Unix systems. I think this may be useful to some people. This is the URL: http://izumi.plan99.net/blog/?p=19 I've search quite a lot for similar solutions, but I seem to be the first one to do this. It was fairly trivial, I only spent half a day on this. I wonder why this hasn't been done before.
