At this stage in the game, I think we should look at doing three
 (1) reverting the UI change, it is a bandaid fix to a deeper
 (2) shipping GNOME 2.14 with gtk-engines 2.6, leaving people who
     giving us more time to optimise gtk-engines/cairo/X
 (3) attempting to profile Nautilus and find out why it is that
     little bit slower

It will be absolutely appaulling if we ship Cairo based gtk-engines
(which most people will not appreciate) while claiming that we've
sped up all these things (pango, GSlice, etc.) only to have all of
our actual window drawing shot to pieces. Once we're on 2.15, we can
start using the new gtk-engines again, hopefully with Cairo 1.2 and
start looking at what is making it slow (still).

People have suggested adding D-BUS interfaces to Nautilus to know
when the background is done being changed, but I think this is also
unrequired. We obviously have a fast code path and a slow code path,
and there has to be a logical explanation for this. If it is
unfixable, then perhaps D-BUS should be our bandaid.
