A further aspect of this that has been bothering me, is why it doesn't 
show up in all the occurrences of (make-stack *cont*) that my debugging 
code does when called from one of the eval trap handlers.  The answer (I 
believe) is that the eval trap handlers don't use real continuations; 
they use "debug objects" instead; this is controlled by the 'cheaptraps 
debug option, which defaults to "yes".

And one more problem ... the same problem exists in CVS head, but a 
similar patch doesn't fix it ... still investigating.
