It is so "awesome" that the GIMP on Ubuntu 14.04 running X11 Unity LightDM (I guess, I don't really know how to tell, I am just looking in the results of "ps aux") when I tell it to load a bunch of files and then -- you know, because this is supposed to be a system that supports multitasking of things -- try to go browse the web that every time GIMP starts loading a new file it forces itself to the front of the desktop stack.
