Do you have an idea of the memory overhead of keeping the source code around?

Is it worth having the ast module honour the __debug__ flag (-O and -OO switches), and *not* preserve source when optimizations are in effect? That may mean that some ast operations cannot run under -O or -OO, in the same way that code that cares about __doc__ strings cannot meaningfully run under -OO. That's okay by me.
