I suspect 100 forked processes that don't load any modules would use a lot less than 40MB, and it only gets worse for threads when you start loading enough modules to do something useful. The code and variable storage used by the modules will all be duplicated into every thread. With forking, copy-on-write prevents this. Forking is not great, but at this point it's a lot lighter than threads.
