I, for one, believe this could be the issue making home directory
loading slower than other directory for a simple reason :

The cost of the Gnome VFS callback is nothing, but the icon are 
only discarded at drawing time.

As we only draw by group of file, this introduce latency (first
files listed are hidden file). So you don't see anything happening
(I mean drawn) until the whole list of hidden file was walked throught.

what do you think ?

What about introducing a special case for this bug,
and revert to the old behavior ? That seem saner to me.

I'm willing to look at this... If nobody else want to do it...
Darin, I'll probably need your help trought.
