Subject: [PATCH] Require Stack to be 'static

Our strategy of leaking the Stack to ensure safety is only effective if
the lifetime of the underlying stack memory is controlled by the
destructor of the Stack. We don't add this bound to unsafe_new, so that
users who wish to provide the necessary guarantees themselves can do so.
