Oh, I see, of course it is.  The problem is that it commits to all 
levels, so that if we happen to be in a nested tentative parse we can't 
commit to the inner one without committing to the outer one, which might 
not be appropriate.  This seems like a basic flaw in our tentative 
parsing mechanism.

What happens if we disable that commit entirely?
