        Sure - it is this change; and yes - if we install schemas individually
it's far, far slower - because we strip out the l10n translations and
merge them into separate files.

        Yep - we need to install multiple .scheme files at once; for gconf
itself that means the:

         ls /etc/gconf/schemas/*.schema | xargs \
                gconftool-2 --makefile-install-rule

        ie. if we only run one gconftool-2 - and get it to merge multiple
schemas we get a linear speedup.

        What would also help is eg. stopping compiz installing 80 separate
schema files ;-).

        But it should be trivial enough to get some big wins here. I wonder how
Fedora & Debian do this - given that they also have merged gconf XML:
presumably they glup schema installs together (?) - or perhaps they run
a gconf daemon during install [ which is riskier and nastier I guess ].

        I guess the same fixes to libgnome, and gnome-settings-daemon would be
worthwhile, gnucash seems to install umpteen schemas, the panel and
evince would be the others I suppose.

        HTH,

                Michael.
