 A @deftech{continuation barrier} is another kind of continuation frame
 that prohibits certain replacements of the current continuation with
 another. Specifically, a continuation can be replaced by another only
-when the replacement does not introduce any continuation barriers (but
-it may remove them). A continuation barrier thus prevents ``downward
-jumps'' into a continuation that is protected by a barrier. Certain operations
-install barriers automatically; in particular, when an exception
-handler is called, a continuation barrier prohibits the continuation
-of the handler from capturing the continuation past the exception
-point.
