  Okay, I reviewed the patches, they are okay, except the freeing was
leaking all the strings from the memory and processor arrays. it was
easy to fix.
  I think it's okay to add this based on the fact we want extend libvirt
toward being an entry point for management tools, but that's on the
edge since it's not really specific to virtualization (and where needed
i.e. CPU flags and memory hierarchy) those informations are already
provided.
  My question is "do you need all those informations ???", my concern
is that already on my small desktop the output is 3KB and I assume on a
very large box we could hit hundreds of kilobytes.
  Also empty entries (i.e. zero lenght or spaces) should IMHO be
removed.

  I'm ready to commit those with the memory leak fixes, but a bit more
feedback would be welcome :-)
