Comment 4 for bug 44002

This problem is made a LOT worse when using a Live CD. In fact, the first time the menu is opened, it can cause the CD to spin up again, with a long delay. If these icons were loaded into memory on startup of gnome-panel (during which the user is waiting around for gnome to start anyway), the delay would not be present.

Is this a more general problem than just gnome-panel? Does this apply to all icons in GTK menus? Perhaps GTK should preload all the icons whenever the application is started?
