Well, the user interface itself doesn't use GEGL, but if you mean "how 
do I make GIMP use GEGL for image compositing?", the answer is that you 
just turn it on with View -> Use GEGL.

GEGL does not yet do multi threaded, but it a planned feature. It will 
happen transparently to clients though so the GIMP code will not (should 
not have to) bother.
