Concerning thread-safety and continuation safety: as long as
continuations aren't resumed multiple times (*), and as long as no
closures are passed, then the mutation doesn't make any observable
difference (except fastness).
(*) E.g., the continuations that guile-fibers construct are resumed
only once.
