Why wouldn't it if you use dynamic-wind? The thunk is exited by
calling (exit), isn't it? So I would *expect* it to call the 'after'
part of the dynamic-wind. Just from reading the standard I would never
consider the possibility that a program ever leaves the thunk without
calling the 'after' part.
People use dynamic-wind because they *want* the 'after' part to be called
whenever the thunk is exited.
