For testing, I changed utilities/imageeditor/editorwindow.cpp:

- EditorWindow::EditorWindow(const char *name)
-           : KMainWindow(0, name, WType_TopLevel)
+ EditorWindow::EditorWindow(const char *name)
+           : KMainWindow(0, name, WType_TopLevel | WDestructiveClose)

which showed substantial reduction in memory when editor window is
closed without any perceivable slowness in reopening the editor window
(I opened/closed the editor window a number of times on different
pictures). Is the hiding of the editorwindow instead of deleting it
_intentional_ ?

Thanks,
