It is possible to implement thunks without them creating their own frame. They can reuse the frame of the surrounding function. So a new frame does not need to be created when the thunk is called, and, much like with a yield statement, the frame is not taken down when the thunk completes running. The implementation just needs to take care to save and restore members of the frame that get clobbered when the thunk is running.

Woo. That's cute.

Cheers, mwh
