In all likelihood, if your data is of a size where you need to be worried about freeing the memory, you'd be better off to investigate other ways of storing it, such as a database, that don't require it to all be in memory at once. Maybe if you explain the reason you are worried about memory consumption to us, we could understand what you're trying to do better and perhaps suggest a better alternative.

Getting away from trying to micromanage memory allocation is one of the principal advantages of modern scripting languages--why exactly are you trying to out-think the compiler?
