It makes no difference what so ever.  The only difference I see so far
between auto_layout+tight-layout and auto_layout+non-tight-layout is
that the latter uses STANDARD_ICON_GRID_WIDTH as it's default minimum
width for icons i.e. both use lay_down_icons_horizontal function to do
layout.  

The problem here is that nautilus is using layout functions to update
icon captions.  I pretty sure that nautilus copy operation (I have not
taken look at that code yet) is using an idle function to do its work
which periodically directly or inderectly triggers layout_changed signal

I observe that if gtk is not idle that nautilus seems (it might
actually) to suspend copy operations until gtk become idle, this is in
my opinion is a serious flaw.  Does not gnome-vfs use threads for file
operations anyway?

P.S. I also dont like the non-tight layout for the same reason.  I
dislike also that auto-layout mode does not align the icons by columns,
but I am trying to fix that myself.
