OK, got to those as well. I have put them in 'devel/for-jens-4.5' and
are going to test them overnight before pushing them out.

I see two bugs in the code that we MUST deal with:

 - print_stats () is going to show zero values.
 - the sysfs code (VBD_SHOW) aren't converted over to fetch data
   from all the rings.
