There are, in fact, hard realtime garbage collection algorithms available. For some reason language designers just don't seem to want to implement them in their languages in favour of garbage collection algorithms that are easier to write. What I'd like to see someday is a language whose runtime explicitly supports garbage-collection plug-ins so that you can use the appropriate collection algorithm for the appropriate situation. Going to the OP's question? Embed the Lua. Ruby is a great language and great for embedding in applications, even, except in the specific case of what you're talking about right now: anything with hard realtime (and even soft realtime!) requirements. Lua is a much faster language and has garbage collection that is far more easily tuned. --=20 Michael T. Richter (GoogleTalk: ttmrichter@gmail.com) I have to wonder why people think that when they can't manage local personnel within easy strangling and shooting distance, then they can manage personnel thousands of miles away that have different languages, cultures, and business rules.
