Guile's continuation barriers have a catch-all so they return only once. (We probably need to support some other form of continuation barriers that allow local escapes -- as per http://thread.gmane.org/gmane.lisp.scheme.plt/40465 -- but that's another issue.)

Anyway it is possible to do an escape from a continuation barrier with an abort to a prompt, I think. That should be fixed.
