GConf could probably be patched such that it writes unformatted XML to
disk.  Yup, it looks like XML_SAVE_FORMAT is something inside libxml.

for performance increases.  The decrease in legibility may be worth a
large jump in conffile parsing.  But something small like 10% is
probably not a big deal.
