Hi Oliver,

I've attached the patch for your review.  In addition to the items listed
above, I also made a few other minor changes to better handle some error 
conditions I ran into while testing the patch, I renamed a few functions and
macros to be more related to their actual purpose, globally exposed just the
single-page dump callback function, and made it return a legitimate return value.
(And there may be other minor changes that I can't remember.)  

Let me know what you think about the changes, and if we're in agreement,
I'll check it in tomorrow.

Thanks,
  Dave
