I hope to eventually (gnome 2.2 timeframe) rewrite the icon factory to use 
GnomeIconLoader. This means we will support the new icon theming spec, and 
I especially designed the spec and GnomeIconLoader to avoid this crap.

It is my belief that we will get a significant speedup from this. icon 
factory stuff seem to be taking about 1/3 of the time when loading a large 
directory.

I need to think a bit how this would match the new icon theming. But 
something like this needs to be done.
