Sorry, not true. The image's first display takes ownership of the image,
further displays merely ref it. gimp_image_delete() has no effect when
there is a display, and for images with displays you would delete all
displays to get rid of the image.

Tom, try doing this in a loop like 100 times, the memory consumption
will stay about the same. There is a lot of memory caching going on in
glib and gimp.
