The nasty thing about a space leak as compared to a traditional memory leak is that the thunk will likely get evaluated or discarded eventually. That's a good thing in that the memory used often won't grow unbounded in a long-running process, it's just larger than it should be, but it makes it way harder to find the source of the problem.
